Abstract:
A process for producing a laminated ink-jet recording head comprising a spacer in which a pressure generating chamber is formed, a diaphragm that closes one side of said pressure generating chamber and which has a piezoelectric vibrator of a flexural vibrating mode secured thereto, and a nozzle plate which closes a second side of said pressure generating chamber and which has a nozzle orifice bored for the issuance of ink drops, said process comprising the steps offorming a titanium layer across one surface of said diaphragm,forming a gold layer which is open in at least a region that corresponds to the pressure generating chamber,forming a layer of a piezoelectric material on said titanium layer by a hydrothermal method using said gold layer as a mask,removing said gold layer, andforming an electrode on said layer of a piezoelectric material after the removal of said gold layer.
