Method of forming an ink jet recording head having an orifice plate with positioning openings for precisely locating discharge ports in a recording apparatus
 An ink jet recording apparatus comprises a recording head for recording on a recording medium, which recording head includes a head body member having a plurality of thermal energy generating elements to discharge liquid for recording and an orifice plate having a plurality of discharge ports for discharging liquid therethrough in response to the thermal energy generated by the generating elements. The orifice plate includes a junction portion attached to the head body member, extension portions protruding from two ends of the junction portion and positioning openings in the extension portions, which positioning openings are precisely located relative to the discharge ports. The apparatus includes positioning pins flanking a head-mounting opening in the apparatus that accepts the head body member, and the positioning pins cooperate with the positioning openings to accurately position the discharge ports in the apparatus when the head body member is inserted in the head-mounting opening.
