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 common recess, grooves, and common recess and/or column members (7) in the grooves are formed on a base board at the same time, and such board is made a second base board (5), which is coupled to a first base board (2) on which elements (1) for liquid discharging energy are formed; hence obtaining an ink jet recording head provided with a filter unit in an arbitrary position in the region formed by the ink paths and the common liquid chamber (4). The filter unit (8) can be processed by a single processing in the ink paths and/or the common liquid chamber (4) to make it possible to prevent disabled discharge from taking place due to dust particles intermingled at the time of head manufacture. In this way, the discharging stability is enhanced, making a high-speed printing possible. A work is efficiently processed by a single processing which is performed to process a three-dimensional configuration with respect to the direction in which the laser beam is irradiated.
