Abstract
A liquid ejection head has a first substrate, a second substrate, and a damper member suppressing vibrations of a liquid. The damper member bonds the first substrate and the second substrate to each other by an adhesive agent. The damper member has a first area sandwiched between the first substrate and the second substrate and a second area not sandwiched between the first substrate and the second substrate. In the second area, the adhesive agent adheres to the side surface of the damper member so as to fix the damper member firmly.
