<p>The purpose of the present invention is to make it possible that in an inkjet head provided with three or more channel rows, the channels are reliably sealed by an adhesive. An inkjet head comprises: a head chip (1) which is configured by arranging three or more channel rows and disposing drive channels (11a) and dummy channels (11b); and a wiring substrate (3) which has ink flow path ports (31) and wiring electrodes (32), is joined to a back surface (1b) of the head chip (1) such that the edge portion thereof protrudes from the sides of the head chip (1) to electrically lead out drive electrodes to the edge portion via connection electrodes and the wiring electrodes (32), and closes openings of the dummy channels (11b), the inkjet head being characterized in that in the head chip (1), the connection electrodes of the dummy channels (11b) and/or the drive channels (11a) in at least one channel row located inside among the three or more arranged channel rows are each formed so as to surround the opening of the channel.</p> |
