Patent ID: 8359747

Claim:
A method for manufacturing a liquid ejecting head comprising a channel forming substrate and a reservoir forming substrate, the method comprising: forming a vibration plate on the channel forming substrate; forming a piezoelectric element on the vibration plate; removing portions of the vibration plate in order to form a first opening portion and a second opening portion; forming a lead electrode extending from the piezoelectric element, a first separate metal layer disposed over the first opening portion and a second separate metal layer disposed over the second opening portion, the separate metal layers being disconnected from the lead electrode; attaching a reservoir forming substrate to the one surface of the channel forming substrate; forming a communicating portion including forming a first positioning hole in a region where the first opening portion is formed in the channel forming substrate and forming a second positioning hole in a region where the second opening portion is formed in the channel forming substrate; and communicating the reservoir portion with the communicating portion and communicating the first positioning hole with the second positioning hole by removing the separate metal layers in a wet etching process; wherein the first separate metal layer and the second separate metal layer are electrically connected.
