ABSTRACT:
A nozzle sheet has arrays of nozzles, and additionally has two first positioning holes on opposite sides of the arrays of nozzles, respectively, that are opposite to each other in a lengthwise direction of the nozzle sheet, and two second positioning holes in respective vicinities of the two first positioning holes. When the nozzle sheet is adhered to a lower surface of a channel unit consisting of a plurality of sheet members and having a plurality of ink channels, first, two first positioning pins of a first jig are fitted in the two first positioning holes of the nozzle sheet so as to position the nozzle sheet relative to the first jig and, subsequently, the channel unit is adhered to the nozzle sheet so as to provide a cavity unit. When a plurality of ejector units each of which includes an actuator fixed to an upper surface of the cavity unit are fixed to a frame member of an ink jet printer head, such that the ejector units extend parallel to each other, first, two pairs of second positioning pins of a second jig are fitted in the respective pairs of second positioning holes of the respective nozzle sheets of the ejector units and then the ejector units are fixed with an adhesive to the frame member.
