Abstract
An inkjet head includes a cavity plate having a plurality of pressure chambers arranged in matrix, a piezoelectric sheet laminated on the cavity plate, and a power supply board. A plurality of substantially rhombus driving electrodes are formed on the piezoelectric sheet in a matrix at positions corresponding to the pressure chambers. A first contact land extends from one of the acute angle corners of each driving electrode. The driving electrodes are arranged such that the first contact land extending from one driving electrode is placed between two driving electrodes adjacent to said one driving electrode. The power supply board has a plurality of second contact lands formed at positions corresponding to the first contact lands. The second contact lands are connected with respective ones of the first contact lands for power supply.
