    摘要： A method of forming an ink jet recording head having a passage forming substrate made of a silicon monocrystalline substrate, having pressure generating chambers communicating with nozzle orifices, and having piezoelectric elements. Grooves, extending in the longitudinal direction, are formed on both sides of a region where the pressure generating chamber is to be formed in a surface of the passage forming substrate. Etching stop layers are provided to restrict the etching of the passage forming substrate. Pressure generating chambers are formed by etching out at least a vibration plate side of the passage forming substrate by an etching process so that the etching stop layers are exposed. Piezoelectric elements are formed by successively laminating a lower electrode, piezoelectric layer, and an upper electrode on the passage forming substrate.
