The purpose of the present invention is to provide an ink-jet head which enables the disposition of wiring electrodes at high density and can easily support an increased density of channels. An ink-jet head comprises a head chip (1) in which drive channels and dummy channels are alternately disposed, and a wiring substrate (3), and is characterized in that in the wiring substrate (3), through-holes for supplying ink are formed only at positions corresponding to openings of the drive channels, at least one wiring electrode passes between adjacent through-holes in at least one row of through-holes among a plurality of rows of through-holes corresponding to channel rows and extends to an end of the wiring substrate projecting sideways from the head chip, and at least one wiring electrode passing between the through-holes is not in contact with an opening of the dummy channel and overlaps with the opening of the dummy channel as seen from an ink discharge direction. |
