PROBLEM TO BE SOLVED: To provide an inkjet head capable of preventing a dummy channel from being blocked by an adhesive and stably discharging ink by optimizing a state of adhesive fillet in an opening of the dummy channel.SOLUTION: An inkjet head includes: a head chip having a channel row in which a channel and a drive wall 12 are alternately arranged and a channel opening 110 arranged on a front surface and a rear surface of the head chip; and a wiring substrate joined with the rear surface of the head chip so as to cover the channel row. The channel row has a drive channel 11a and a dummy channel 11b that are alternately arranged. The wiring substrate has a through hole for supplying ink at a position corresponding to the opening 110 of the drive channel 11a and blocks the rectangular opening 110 of the dummy channel 11b by being joined with the rear surface of the head chip by an adhesive 6. An adhesive fillet 61 formed by the adhesive 6 in the opening 110 of the dummy channel 11b is independently made to exist at four corners of the opening 110. |
