ABSTRACT:
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.
