Abstract:
1. A liquid ejection head comprising: a nozzle plate having a nozzle array constructed of multiple nozzles from which liquid droplets are ejectable; a channel member that forms multiple individual channels respectively communicating with the multiple nozzles; a pressure generator to pressurize liquid within the multiple individual channels; and a common channel member that forms a common channel from which the liquid is supplied to the multiple individual channels, the channel member comprising: a first surface facing the common channel member and having inlets respectively communicating with the multiple individual channels; a second surface provided at both ends of the channel member in a direction in which the nozzle arrays extend, the second surface facing the common channel member and protruding beyond the first surface toward a direction opposite a direction of flow of the liquid from the common channel into the inlets; and a third surface that connects the first and second surfaces, at least a gap between the common channel member and a part of the second surface being sealed by a seal member that forms a wall of the common channel between the channel member and the common channel member in the direction in which the nozzle arrays extend, wherein a bonding portion of the second surface of the channel member is bonded to the common channel member, and a distance between the common channel member and the bonding portion of the second surface is smaller than a distance between the common channel member and the first surface.
