Patent ID: 8459781

Claim:
An inkjet head comprising: an actuator which includes an elongated main body and a plurality of grooves, the main body including a front surface, a back surface, and a pair of side surfaces, the side surfaces connecting the front surface with the back surface and being inclined from the front surface toward the back surface to go away from each other, the grooves being arranged at intervals in a longitudinal direction of the main body and configured to be continuously opened to the front surface and the side surfaces of the main body; a substrate which includes a mounting surface on which the main body of the actuator is mounted, and a plurality of inflow parts that are opened to the mounting surface; an adhesive layer which fixes the actuator onto the substrate, the adhesive layer being interposed between the actuator and the mounting surface of the substrate to cover an open end of each of the inflow parts, and including an end part which is exposed between each side surface of the actuator and the mounting surface of the substrate; and a plurality of insulating patterns which are provided on a conductive layer that covers the side surfaces of the actuator, internal surfaces of the grooves, the end part of the adhesive layer, and the mounting surface of the substrate, the insulating patterns running between the grooves and extending to the mounting surface of the substrate through the end part of the adhesive layer, and being configured to divide the conductive layer into a plurality of electrodes that correspond to the respective grooves.
