摘要： A method for manufacturing an orifice plate used for a liquid discharge provided with discharge port for discharging liquid comprises the steps of preparing a non-conductive plate having recessed portion formed on the circumference of the flat portion corresponding to the discharge port, forming a first conductive material peelable from the non-conductive plate only in the recessed portion of the non-conductive plate, forming a plate member by plating the first conductive material with a second conductive material by electroforming method after the formation of the first conductive material, and obtaining the orifice plate having the discharge port by peeling off the plate member from the non-conductive plate. With the method thus arranged, it is possible to materialize the same precision as in the glass mask used for photolithography, and make the variation of orifice areas smaller for the formation of highly densified orifices.

摘要： A liquid discharging method for discharging liquid, which uses the pressure exerted at the time of creating each of bubbles in liquid in a bubble generating area, is arranged to provide two bubble generating areas for generating bubbles in such a manner as to enable these areas to face each other at least partly, hence discharging liquid by means for the pressure thus exerted in the bubble generating areas. In this way, it becomes possible to increase the amount of liquid discharged, as well as to enhance the durability of the movable members, while stabilizing the discharge of liquid from each of the discharge openings.

摘要： An ink jet recording head, which can be used in a recording apparatus, is manufactured by preparing a first base plate provided with an energy generating structure for generating energy to discharge ink, preparing a second base plate provided with a discharge opening plate member on which are to be formed ink discharge openings for discharging the ink and recessed portions for forming ink flow paths, the ink flow paths being communicated with the discharge openings, and applying an ink repellant treatment on a surface of the discharge opening plate at a side where the ink is to be discharged in at least an area where the discharge openings are to be formed. The discharge opening is formed on the discharge opening plate by irradiating a laser beam on a rear surface of the discharge opening plate at the opposite side from where the ink is discharged, and the first base plate and second base plate are connected so that the energy generating structure and recessed portion face one another to form the ink flow paths.
