Abstract
Official abstract text for this publication.
A liquid jet head is provided with laminated head chips forming a laminated structure. Each of the head chips has an actuator portion and a nozzle plate bonded to a first end face of the actuator portion. The actuator portion of each head chip has a filter, a first liquid chamber communicating to a downstream side of the filter, a channel communicating to the first liquid chamber for inducing pressure on liquid therein, and an electrode terminal for transmitting a drive signal to the channel. The nozzle plate has a nozzle communicating to the channel of the actuator portion. The surfaces of the nozzle plates of the respective head chips are flush with one another.
