Abstract
A recess is formed in a surface confronting an actuator unit of an ink supply inlet forming substrate. When a flow path unit and the actuator unit are bonded together using a fusible film, thermally expanded air is released into the recess to thereby reduce pressure. Further, by arranging the recess at a position confronting a pressure generating chamber, an air layer formed by the recess is allowed to function as a vibration shielding member.
