摘要： A cavity unit of an ink-jet printhead is formed by laminating a base plate formed with pressure chambers, a spacer plate, a manifold plate, a damper plate, a cover plate, and a nozzle plate formed with nozzles. The manifold plate is formed with a manifold chamber that penetrates through the manifold plate. The damper plate is formed with a recess on a side facing away from the manifold chamber and a damper wall left on a side facing the manifold chamber to have a partial thickness of the damper plate. The damper plate is bonded to the manifold plate on an opposite side from the base plate such that the damper wall is positioned to face the manifold chamber. The cover plate is bonded to the manifold plate to seal the recess. Because the damper plate is relatively thick while the damper wall is thin enough to absorb a pressure wave in the manifold chamber generated upon ink ejection, the damper plate is easy to handle.
