PROBLEM TO BE SOLVED: To provide an inkjet head in which the electrical connection of drive wirings to each of the channels in neighboring two rows of channels in a harmonica type head chip can be easily made only at one edge part of the head chip, and also only the side of the same surface as the surface which is joined with the head chip. SOLUTION: In the harmonica type head chip 1 having a plurality of rows of channels (row A and row B), connection electrodes 14A for row A and the connection electrodes 14B for row B formed on the back surface of the head chip 1 are connected to a multilayer member 3 having an insulating layer on one surface of which are formed the lead wirings 32A for row A and on the other surface of which are formed the lead wirings 32B for row B, and extended to protrude outwards from the end on the side of the rows of channels of row A. The lead wirings 32B for row B are extended to protrude from the end of the insulating layer more outwards than the lead wirings 32A for row A at the extended end of the multilayer member 3, and drive wirings are electrically connected to the lead wirings 32A for row A and the lead wirings 32B for row B on the side of the same surface as the surface which is joined with the head chip 1.
