摘要： PROBLEM TO BE SOLVED: To prevent malfunction due to the head bonding between a flow passage unit and an actuator unit, crosstalk or the like from occurring. SOLUTION: A recessed part 21a is formed on a surface opposite to an actuator unit 1 of an ink feeding port forming board 21. When a flow passage unit and the actuator unit 1 are bonded together through a hot welding film, the pressure of thermal expanded air is lowered by allowing it to escape to the recessed part 21a. In addition, by providing the recessed part 21a at the position opposing to a pressure generating chamber 4, the air layer by this recessed part 21a is functioned as vibration interrupting material.

摘要： PURPOSE: To secure the full compliance to the dropwise delivery of ink by removing easily the air bubbles which have entered a common ink chamber and increasing the size of the common ink chamber. CONSTITUTION: A flow passage limiting hole 12 is formed close to a wall face 19a at a distance from the nozzle opening side of a common ink chamber 19, a dummy pressure producing chamber 4' is provided at the end part of the common ink chamber 19 and a plurality of flow passage limiting holes 12' are formed in communication with the dummy pressure producing chamber 4' and in the width direction of the common ink chamber 19. The ink near the wall face 19a is allowed to flow in a set direction away from the wall face and directed in a certain direction due to the resistance of the ink to adherence and air bubbles are carried off in this stream and from the flow passage limiting hole 12 they are sucked into the pressure producing chamber 4 and then dischaged to outside. Due to the formation of the plurality of the flow passage limiting holes 12 near the end part of the common ink chamber 19, even if the width in this region is increased, the stagnation of the ink is not caused.
