Abstract:
A liquid ejection head includes nozzles, a channel member, a common liquid chamber member, a damper member, a damper chamber formation member, a first adhesive, and a second adhesive. The channel member includes individual liquid chambers communicated with the nozzles. The common liquid chamber member forms a common liquid chamber to supply liquid to the individual liquid chambers. The damper member has a deformable area forming a portion of a wall of the common liquid chamber. The damper chamber formation member forms a damper chamber disposed opposing the common liquid chamber via the deformable area. The first adhesive is disposed between the damper member and the common liquid chamber member. The second adhesive is disposed between the damper member and the damper chamber formation member. The deformable area of the damper member has a peripheral portion fringed with the first adhesive and the second adhesive.
