Abstract
A method for manufacturing a liquid ejecting head that has a channel forming substrate and a reservoir forming substrate is provided. The method includes forming a vibration plate on the channel forming substrate, a piezoelectric element on the vibration plate removing portions of the vibration plate to form first and second opening portions, forming a lead electrode extending from the piezoelectric element including a first separate metal layer disposed over the first opening portion and a second separate layer disposed on the second opening portion, attaching a reservoir forming substrate to the channel forming substrate, forming a communicating portion in the channel forming substrate with a first positioning hole corresponding to the first opening portion and a second positioning hole corresponding to the second opening portion, and communicating the reservoir portion and the communicating portion by removing the separate metal layers.
