摘要： An ink supply communication path is formed so that one end thereof is arranged outside a region confronting a pressure producing chamber at a region confronting a reservoir chamber; and an ink supply constricted port is arranged at a portion of the ink supply communication path, the portion being remotest from the pressure producing chamber. Since the pressure producing chamber is connected to the ink supply constricted port through the elongated ink supply communication path, a jet flow from the ink supply constricted port grows into a large flow along the ink supply communication path, which in turn allows air bubbles susceptible to stagnation in the vicinity of the ink supply constricted port to be discharged by such large flow.
摘要翻译：形成供墨连通路径，使其一端配置在面对储存室的区域的与压力产生室相对的区域的外侧; 在供墨连通路径的一部分设置供墨收缩口，该部分与压力产生室最远。由于压力产生室通过细长的供墨连通路径连接到供墨收缩端口，所以来自供墨收缩端口的喷射流沿着供墨连通路径增长成大流量，这又允许气泡易受由于这样大的流量，墨水供应收缩口附近的滞留被排出。

摘要： 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.
