摘要： A method for manufacturing a fluid ejecting head includes providing a channel unit including a vibrating plate and having nozzle opening through which fluid is ejected and pressure chamber that communicate with the nozzle opening. A piezoelectric unit includes a piezoelectric element that vibrates the vibrating plate of the channel unit. A securing plate secures the piezoelectric element. A head case having a housing chamber is used to house the piezoelectric unit, such that the piezoelectric element is pressed against the vibrating plate. The piezoelectric unit is pushed in a housing direction such that a portion of the piezoelectric unit is pressed against a sidewall of the housing chamber. The piezoelectric element and the vibrating plate, and the securing plate and the head case, respectively, are secured to each other by bonding them together while the piezoelectric unit is being pressed against the vibrating plate and the sidewall.

摘要： A method for manufacturing a fluid ejecting head includes providing a channel unit including a vibrating plate having nozzle openings through which fluid is ejected and a pressure chamber that communicates with the nozzle openings. A piezoelectric unit includes a piezoelectric element that vibrates the vibrating plate of the channel unit and which includes a securing plate which secures the piezoelectric element. A head case having a housing chamber houses the piezoelectric unit which is pressed against the vibrating plate in a housing direction such that a portion of the piezoelectric unit is also pressed against a sidewall of the housing chamber. The piezoelectric element is secured directly the vibrating plate and the securing plate is secured directly to head case using a bonding process which is performed while the piezoelectric unit is being pressed against the vibrating plate and the sidewall.

摘要： A conductive nozzle plate is formed with a nozzle orifice. An insulative layer is formed on a first face of the nozzle plate. A head body includes a pressure chamber adapted to contain liquid therein and a pressure generating element operable to cause pressure fluctuation in the liquid. The head body is attached to a second face of the nozzle plate so as to communicate the pressure chamber with the nozzle orifice. The second face of the nozzle plate and the head body are fixed to a head case. A conductive head cover covers a part of the first face of the nozzle plate while exposing the nozzle orifice. A part of the nozzle plate and the head cover directly come into contact with each other.
