Liquid ejecting head and liquid ejecting apparatus

摘要

A liquid ejecting head includes generating chambers communicating with nozzles, a manifold communicating with the pressure generating chambers, a flexible member that has a compliance region, which is able to perform deflection in response to pressure fluctuation in the manifold, a compliance space disposed on a side opposite to the manifold through the flexible member, a cap member facing the flexible member through the compliance space; a frame-like member disposed between the flexible member and the cap member, and an island-like member to be disposed in the compliance region and separated from the frame-like member. One surface of the frame-like member faces the flexible member and the other surface faces the cap member. In a direction in which the flexible member and the cap member face each other, the island-like member is thinner in thickness than the frame-like member.

1. A liquid ejecting head comprising:
a plurality of pressure generating chambers communicating with nozzles through which a liquid is ejected; a manifold communicating with the plurality of pressure generating chambers; a flexible member that has a surface on one side which defines at least a part of a wall of the manifold, that has a surface on the other side, on which an adhesive layer is formed, and that has a compliance region, which is able to perform deflection in response to pressure fluctuation in the manifold, in a region in which the adhesive layer is formed; a compliance space disposed on a side opposite to the manifold through the flexible member; a cap member facing the flexible member through the compliance space; a frame-like member disposed between the flexible member and the cap member; and an island-like member provided between the flexible member and the cap member to be disposed in the compliance region and to be separated from the frame-like member, wherein one surface of the frame-like member on one side facing the flexible member and the other surface thereof on the other side facing the cap member are fixed to the facing members, respectively, wherein any one surface of one surface of the island-like member on one side facing the flexible member and the other surface thereof on the other side facing the cap member is fixed to the facing member and the other surface is not fixed to the facing member, and wherein in a direction in which the flexible member and the cap member face each other, the island-like member is thinner in thickness than the frame-like member.
