Each individual head includes an individual head member having a main surface, a backside surface, a first side surface, and a plurality of second side surfaces. The first side surface includes a plurality of ink jet outlets aligned in a direction parallel to the main surface. Each individual head member includes a plurality of ink paths to supply ink to the plurality of ink jet outlets respectively. Each individual head includes a plurality of drive elements provided on the main surface corresponding to the plurality of ink paths respectively to generate pressure at the plurality of ink paths, and a plurality of electrodes provided corresponding to the plurality of drive elements to apply voltage individually to the plurality of drive elements. The plurality of electrodes have one ends connected to the plurality of drive elements, and the other ends arranged extending up to the neighborhood of any of the plurality of second side surfaces. The plurality of individual heads are stacked in a step-graded manner so that the other ends of the plurality of electrodes are exposed at the neighborhood of the second side surface.
