Zusammenfassung:	An inkjet head employed in an inkjet printing apparatus includes a main body (8) provided with a printing surface, which has a substantially rectangular elongated shape, and a plurality of piezoelectric modules (18). Each of the piezoelectric modules has a substantially trapezoidal shape, and is provided with a plurality of piezoelectric unit structures (18a). The plurality of piezoelectric modules are arranged along a longitudinal direction of the printing surface such that upper base of the trapezoidal shape is located at a central portion in a direction perpendicular to the longitudinal direction. Further, the plurality of piezoelectric modules are oriented in opposite directions alternately in the direction perpendicular to the longitudinal direction.
