An inkjet recording device (1) of the present invention includes an inkjet head (2) and a cap (76). The inkjet head (2) includes a passage unit (104) formed by a lamination of at least one plate (122-129) and a nozzle plate (130). Amongst the plate and the nozzle plate, a plate positioned farther from the nozzle plate (130) has a larger plane shape than a plate closer to the nozzle plate (130) so that the passage unit has, around the entire circumference thereof, a stair-like shaped outer circumferential wall (104a). When the cap (76) covers a plurality of nozzles (108) that the nozzle plate has, the circular protrusion (76a) abuts the outer circumferential wall (104a) of the passage unit (104) so as to enclose the nozzle plate (130) within the recessed portion (78).
