摘要： A laminated body is provided that exhibits impact resistance, wear resistance and scratch resistance, and which enables a reduction in weight together with a reduction in the dielectric constant. The laminated body 100 includes a first tabular member 10 configured from a ceramic material and having a first thickness t1, and a second tabular member 20 configured from a polymer material and having a second thickness t2. The laminated body 100 withstands a falling-ball impact breaking test from a height that is higher than that exhibited by a single layer body that is configured from the ceramic material and of a thickness t3 that is the sum of the first thickness t1 and the second thickness t2.

摘要： In the manufacture of a laminated piezoelectric/electrostrictive element by lamination of a piezoelectric/electrostrictive film and an electrode film containing either platinum or an alloy composed mainly of platinum and having a thickness of 2.0 μm or less, both or either one of yttrium oxide (Y2O3) and cerium oxide (CeO2) is added to the electrode film or the piezoelectric/electrostrictive film, and the electrode film and the piezoelectric/electrostrictive film are fired simultaneously. This simultaneously achieves a reduced thickness and improved thermal resistance of the electrode film and a reduced change in piezoelectric/electrostrictive properties with time, thereby producing a piezoelectric/electrostrictive element with good initial piezoelectric/electrostrictive properties and with a small change in the piezoelectridelectrostrictive properties with time.

摘要： A flow passage component 10 according to an embodiment of the present invention is a component composed of ceramics, which forms a flow passage (R1-R5) through which a liquid flows. The flow passage has a discharge opening (lower end surface of the flow passage R5), at an end of the flow passage, for discharging the liquid in the flow passage to a space outside of the flow passage component 10. The discharge opening is exposed to the outside space. A flow passage wall surface forming the flow passage is covered by/with a protection film (parylene-film) 20 formed of a paraxylylene-based polymer. Further, the parylene-film 20 is formed so as to have its end at a position upstream of the discharge opening by a predetermined distance D along the flow passage wall surface from the discharge opening. This can decrease a possibility that the liquid goes around the “outer wall surface 11a on which the discharge opening is formed.”
