摘要： It is an object of the present invention to ensure a desired precision in positioning an orifice plate with respect to liquid flow paths of a head main body, so as to prevent a failure liquid discharge which will possibly be caused due to a problem involved in a process of forming the orifice holes. In detail, a head main body is formed on the lower wall thereof a plurality of heating elements, has a plurality of liquid flow paths formed by dividing an internal space with a plurality of liquid flow path walls and arranged in parallel relationship with one another. On either side of the plurality of the liquid flow paths there are formed two dummy liquid flow paths. An orifice plate is formed with a plurality of orifice holes arranged in parallel with one another for discharging ink. Further, on either side of the plurality of the orifice holes there are formed two projected portions so shaped that they are capable of engaging with the opening ends of the dummy liquid flow paths. Each of the projected portions is formed with a dummy orifice hole which is not used for discharging ink during recording operation. A desired positioning can be effected by engaging the projected portions of the orifice plate with the dummy liquid flow paths.

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.
