Abstract
A liquid ejection head includes a nozzle, a pressure chamber configured to receive a pressure to eject liquid from the nozzle, a descender, and a communication channel. The descender has a first end and a second end opposite to each other. The first end is connected to the pressure chamber. The communication channel is connected to the second end and extends from a connection with the second end in an X direction. A first direction in which the descender extends from the second end toward the first end is inclined toward the communication channel relative to a Y direction orthogonal to the X direction.
