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.

Liquid ejecting head and liquid ejecting apparatus

A liquid jet head includes: a nozzle plate including a nozzle array, the nozzle array including a plurality of nozzle holes each extending in a Z direction, the nozzle holes being arranged side by side in an X direction; a head chip disposed in a +Z direction with respect to the nozzle plate and including ejection channels communicating with the respective nozzle holes; a manifold disposed in a +Y direction with respect to the head chip, the manifold being configured to support the head chip by a face facing a &#x2212;Y direction and including an ink flow path communicating with the ejection channels; and a drive board supported on the face facing the &#x2212;Y direction of the manifold and electrically connected to the head chip.

Liquid jet head and liquid jet apparatus

A liquid jet head includes: a head chip including a channel to be filled with ink; a manifold that supports the head chip and includes an ink flow path communicating with the ejection channel; and a heater and a drive board that are supported on the manifold and heat ink inside the ink flow path. The ink flow path extends in a meandering manner.
