Abstract
A method of manufacturing an ink jet recording head. On one and the other surfaces of an ink supply plate, formed with a plurality of discrete ink supply ports and a corresponding number of discrete nozzle ports, a green sheet for a pressure chamber plate and a green sheet for an ink pool plate are laminated, respectively. The resulting lamination is then sintered. A vibration plate is subsequently adhered to the pressure chamber plate formed by the sintering step and a nozzle plate is adhered to the sintered pool plate.
