Abstract
Pressure applying sections applying a pressure to ink in pressure chambers are arranged in a staggered array in a sheet feed direction to form a row. Four of such rows of the pressure applying sections are aligned in the scanning direction. One part of inspecting sections among plural inspecting sections detecting resonance frequencies are arranged respectively at positions deviating from both end parts and an approximately center part, in the sheet feed direction, of each row of the pressure applying sections toward both sides in the scanning direction, and are aligned in the sheet feed direction. The other inspecting sections are arranged on both sides, in the sheet feed direction, of the rows of the pressure applying sections, and are aligned in the scanning direction. Further, plural dummy electrodes are aligned with the one part of inspecting sections, the inspection electrodes, and the pads in the sheet feed direction.
