PROBLEM TO BE SOLVED: To provide an inkjet head which makes simple electrical connection between a connecting wiring line led out from a driving electrode of each ink channel and a driving wiring line of a wiring board, facilitates countermeasures against heat radiation of a head chip, and enables stacking in a multi stage shape of two or more stages to form multi nozzles. SOLUTION: The inkjet head has the head chip 1 whereat driving walls 13 comprising piezoelectric elements, and ink channels 14 are arranged alternately, and moreover, outlets 142 and inlets 141 of the ink channels 14 are arranged to be opposite to each other at a front face and a rear face, respectively. The wiring board 3 is joined to the rear face of the head chip 1. The connecting wiring line for electrical connection to each driving electrode set at the driving wall 13 is led out, and at the same time, the driving wiring line 31 for electrical connection to a driving circuit is formed by a pitch corresponding to each of the connecting wiring lines. Ink introduction ports 32 corresponding to the inlets 141 of the ink channels 14 are formed at the wiring board 3. COPYRIGHT: (C)2004,JPO&NCIPI
