<p>PROBLEM TO BE SOLVED: To prevent occurrence of narrowing or clogging of a flow channel caused by flowing out of an adhesive agent when a filter member is allowed to join to a flow channel plate by the adhesive agent.SOLUTION: In a nozzle array direction, an outer periphery 94 constituted of a reinforcement region 92 of a filter region 9A is joined to a partition wall part 51 or the like formed of a flow channel plate 2 by an adhesive agent 81. In the filter region 9A, the filter region 9A is joined to the partition wall part 51 formed of the flow channel plate 2 by the adhesive agent 81, the filter region 9A bends in an opposite direction to a flow direction of liquid from a common liquid chamber 10 to a liquid supply passage 5 (a liquid introduction part 8) in the nozzle array direction, and a filter region 91A is formed such that an interval L2 of a junction surface between the filter region 9A and the partition wall part 51 becomes wider than an interval L1 of a junction surface between the outer periphery 94 and the partition wall part 51 of the filter region 9A of a filter part 9.</p> |
