A pressure chamber of each of channels of an inkjet head has a non-rotating body shape around an axis perpendicular to a support substrate on which the pressure chamber is formed. The direction of the pressure chamber corresponding to a rotation angle from a reference position around the axis passing through the pressure chamber is defined as the direction of the pressure chamber. A plurality of channels arranged in a same row in a direction parallel to the substrate includes channels and having the pressure chamber facing different directions. In a same row, channels (e.g. channel) driven by a same circuit element (e.g. circuit element) are arranged such that the pressure chambers face a same direction.
