摘要：
A liquid ejection head includes a common-chamber formation member including a common chamber to supply liquid to pressure chambers communicating nozzles for ejecting liquid droplets, a flexible thin-film member to form part of a wall face of the common chamber, and a thin-film support member bonded to the thin-film member with glue. The support member has an opening or a recessed portion at least partially having a shape that is broad in an area proximal to a first surface of the support member bonded to the thin-film member and becomes narrower as an area of the opening or the recessed portion is more distant from the first surface. The opening or the recessed portion is sealed with the thin-film member. A portion of the thin-film member corresponding to the opening or the recessed portion has the glue on only a periphery area of the portion that contacts the support member.
