发明名称 Liquid ejecting head and liquid ejecting apparatus
摘要 A liquid ejecting head includes: a flow channel member made of silicon; a nozzle plate made of silicon; a manifold member, which cooperates with the flow channel member to define a manifold in fluid communication with a plurality of pressure generation chambers; and a cover member, wherein the cover member is made of a different material than the nozzle plate, and wherein the cover member is affixed to the surface of the flow channel member that is affixed to the nozzle plate. The cover member fluidly blocks the manifold from the ambient atmosphere.
