A color ink jet printer 21 includes a carriage 26 and a head unit 25 supported to the carriage 26. The head unit 25 includes an ink jet head 24 and a base plate 46. The ink jet head 24 includes an actuator having channel members 72 and a center plate 73 interposed between the channel members 72, and the ink jet head 24 also includes manifolds 71. The center plate 73 has a height grater than that of the channel members 72 so as to protrude upward from the channel members 72. Thus protruding portion is directly attached to the base plate 46. Accordingly, the actuator 70 is reliably supported by the base plate 46, thereby preventing positional deviation of nozzles 75 formed to the actuator 70.
