A pressure chamber (P) in each of the individual channels (21a) of an inkjet head (21) is configured as a body that does not rotate with respect to the axis perpendicular to a support substrate (31) on which the pressure chambers (P) are formed. For a pressure chamber (P), the direction that corresponds to the angle of rotation from a reference position about the above-mentioned axis that passes through the pressure chamber (P) is defined as the orientation of the pressure chamber (P). A plurality of channels (21a) disposed in the same row in a direction parallel to the substrate include channels (21a1) and (21a2) in which the pressure chambers (P) have different orientations. In the same row, channels (e.g., channel (21a1)) driven by the same circuit element (e.g., circuit element (39a)) are disposed so that the pressure chambers (P) are oriented in the same direction. |
