Abstract: According to an embodiment, an ink jet head includes a pair of actuator plates, a return plate, and a flow passage plate. The pair of actuator plates are disposed to face each other in a Y-direction. In the actuator plate, a plurality of channels which extend in a Z-direction are arranged at a distance in an X-direction. The return plate is disposed on an opening end side of the channels in the pair of actuator plates. A circulation passage which communicates with the channels is formed in the return plate. The flow passage plate is disposed between the pair of actuator plates. An inlet flow passage into which an ink flows and an outlet flow passage which communicates with the circulation passage are arranged in the Z-direction.
