PROBLEM TO BE SOLVED: To provide a manufacturing method for an inkjet head wherein an electrical connection between a connection wiring line led out from a driving electrode of each ink channel and a driving wiring line of a wiring board can be simply performed, and also high-density arrangement of nozzles by constructing ink channels of a plurality of arrays is facilitated. SOLUTION: In the manufacturing method for the inkjet head, the connection wiring lines each electrically connected to each driving electrode set at driving walls 13A and 13B are led out to rear faces of head chips 1A and 1B. In the head chips 1A and 1B, the driving walls 13A, 13B consisting of piezoelectric elements and the ink channels 14A, 14B are alternately arranged in parallel, and at the same time outlets 142A, 142B and inlets 141A, 141B of the ink channels 14A, 14B are arranged at front and rear faces, respectively. The wiring board 3, where the driving wiring lines 31A and 31B which electrically connect to a driving circuit by a pitch corresponding to each connection wiring line, and ink communication openings 32A and 32B which penetrate at positions corresponding to the inlets 141A and 141B of the ink channels 14A and 14B are formed, is joined to the rear faces of the head chips 1A and 1B.
