Abstract: An inkjet head has a head chip. The head chip has driving walls of piezoelectric material, which deform by applying voltage, to jet ink. Channels are arranged alternatively, alongside the driving walls and contain ink. Each channel has an outlet and an inlet port at a front and rear surface of the head chip. Driving electrodes, formed on surfaces of the driving walls, apply voltage to the driving walls. Connection electrodes, formed on the rear surface of the head chip, electrically connect to the driving electrodes. A wiring substrate, having wiring electrodes apply voltage to the driving electrode through the connection electrode. The wiring substrate is bonded to the rear surface of the head chip to protrude from the head chip in a direction perpendicular to the direction of the channels so that all the channels are exposed at the rear surface of the head chip.
