Abstract

See full text

A liquid ejecting head includes a flow-path forming substrate including pressure generation chambers that communicate with nozzle openings through which ink is ejected, a piezoelectric element that applies a pressure to the pressure generation chambers via a diaphragm, and a protection substrate that forms a sealed space for sealing the piezoelectric element, in which a pressure in the sealed space is adjusted such that the diaphragm is drawn up to the piezoelectric element side and an initial bent position of the diaphragm is adjusted.
