Abstract
A method of manufacturing a liquid jet head includes a through hole forming step of forming through holes on a base plate, an actuator plate bonding step of bonding actuator plates to opposite sides of the base plate, and an electrode forming step of forming electrodes on the bonded base plate and the actuator plates. In the through hole forming step, the through holes are formed on the base plate and the inner surfaces of the through holes are roughened. In the electrode forming step, second extraction electrodes are routed to a principal surface of the base plate through the through holes.
