A substrate 20 is prepared. “A piezoelectric material layer 32a which has not been fired” and which will become a piezoelectric membrane is formed above a first principal surface 20a of the substrate 20. A first mask 131 is formed above the piezoelectric material layer 32a. “The piezoelectric material layer 32a existing within a portion where the first mask 131 does not exist” is eliminated by injecting a blast media including at least one of abrasive grains or an organic solvent onto the first principal surface 20a of the substrate 20. Thereafter, the first mask 131 is eliminated, and the piezoelectric material layer 32a is fired. The substrate has a hollow portion, however, it does not necessarily have the hollow portion.

A manufacturing method for a piezoelectric/electrostrictive film type element and a film constituting a laminated vibrator made of laminations of an electrode film and a piezoelectric/electrostrictive film in a plane position. The piezoelectric/electrostrictive film type element includes a substrate, a lower electrode film provided on the substrate, and a laminated vibrator made of laminations of a piezoelectric/electrostrictive film and an upper electrode film. The lower electrode film is formed by a photolithography method with the substrate, where a cavity is filled with a light shielding agent, as a mask. Thereafter, the piezoelectric/electrostrictive film is formed by electrophoresis of powder of a piezoelectric/electrostrictive material toward the lower electrode film, and the upper electrode film is formed by the photolithography method with the piezoelectric/electrostrictive film as a mask. The piezoelectric/electrostrictive film may be formed by the photolithography method with the lower electrode film as a mask.

Disclosed is a hair cosmetic which can achieve fixing of hair (hairstyle) by sticking and also has an excellent arranging ability (also including a restyling ability), and moreover has humidity resistance. Specifically disclosed is a hair cosmetic having a novel adhesive setting resin which is obtained by combining and polymerizing monomers having a specific structure and has a moderate firmness and a high adhesive force when forming a film and further comprising a setting agent resin. Accordingly, a hair cosmetic having both fixing ability and arranging ability, and also having excellent humidity resistance (hair set retaining ability) is obtained.

The present invention provides a hairstyling cosmetic that applies easily; fits smoothly to hair; thickens thus has a superior hairstyling capacity immediately after application; and has suitable setting capacity, re-hairstyling capacity, and non-stickiness because upon completion of hairstyling, entire solvent volatilizes and a hairstyling component precipitates. The hairstyling cosmetic of the present invention is characterized by comprising: (a) one or more block-type alkylene oxide derivative(s) selected from formulae (I), (II), and (III), which is solid at room temperature (25° C.) and insoluble in water but soluble in lower alcohols to become transparent; and (b) a solvent containing water and a lower alcohol, wherein the component (a) dissolves in component (b), and as the lower alcohol preferentially volatilizes after application, component (a) is admixed with the solvent with a changed composition, and then substantially entire solvent volatilizes: R1O-[(AO)p(EO)q(AO)r]—R2 (I) R1O-[(EO)p(AO)q(EO)r]—R2 (II) R1O-[(EO)p(AO)qR3(AO)s(EO)r]—R2 (III) wherein AO is an oxyalkylene group having 3 to 4 carbon atoms, EO is an oxyethylene group, p, q, r, and s are the average addition mole numbers, 1≦p+r≦90, and 1≦q+s≦90, the percentage of the oxyethylene groups with respect to the sum of the oxyalkylene groups having 3 to 4 carbon atoms and the oxyethylene groups is 20 to 80 mass %; each of R1 and R2 is a hydrocarbon group having 1 to 4 carbon atoms or a hydrogen atom and they can be either the same or different; and R3 is a linear or branched hydrocarbon group having 1 to 36 carbon atoms.

A piezoelectric/electrostrictive element with improved moisture resistance while having less degradation in its piezoelectric/electrostrictive properties and a method of manufacturing such a piezoelectric/electrostrictive element are provided. A laminated vibrator of a piezoelectric/electrostrictive element has a structure in which an electrode film, a piezoelectric/electrostrictive film, another electrode film, another piezoelectric/electrostrictive film, and another electrode film are laminated one above the other. In the manufacture of the piezoelectric/electrostrictive element, the laminated vibrator and a counter electrode are immersed in an electrodeposition coating fluid containing a coating component so that the electrodeposition coating fluid is brought into contact with the surfaces of the laminated vibrator and the counter electrode. Thereafter, voltage is applied between an internal electrode film and the counter electrode to induce electrophoresis of the coating component toward a surface-exposed defect, whereby the coating material is selectively electrodeposited on the surface-exposed defect.
