Patent ID: 8870347

Claim:
A liquid ejecting head, comprising: a flow channel member, comprising silicon, further comprising: a flow channel substrate defining a plurality of pressure generation chambers; and a communication plate defining a plurality of communication holes, wherein each of the communication holes is in fluid communication with a corresponding one of the pressure generation chambers; a nozzle plate, comprising silicon, wherein the nozzle plate is affixed to a surface of the communication plate, the nozzle plate defining a plurality of nozzles; a manifold member, wherein the manifold member and the flow channel member cooperate to define a manifold, wherein the manifold is in fluid communication with the plurality of pressure generation chambers and extends along a lengthwise direction of the pressure generation chambers; and a cover member, made of a different material than the nozzle plate, wherein the cover member is affixed to the surface of the communication plate to which the nozzle plate is affixed, wherein the cover member fluidly blocks the manifold from an ambient atmosphere of the liquid ejecting head.
