Abstract

PURPOSE:To inject ink without trouble from an ink jet recording head incorporating a filter by forming a sieve shaped at one end section of an ink supply path at the same time as a flow path through photoetching. CONSTITUTION:Grooves corresponding to a filter 6, ink supply paths 4, pressure generating chambers 3, pressure transmitting paths 2 and a nozzle group 1 are dug simultaneously in the direction vertical to a substrate 10 through a photoetching method. Consequently, since the filter is shaped at the same time as flow paths, the diameters of the filter also change similarly to errors on the manufacture of the diameters of nozzles. As a result, pressure generated in the pressure generating chambers is transmitted over the ink supply side, where the filter is arranged, and the nozzle side, but pressure is distributed at a proper value according to a design because the other parties similarly alter, and dispersion due to errors on manufacture has no effect on the characteristics of injection, thus resulting in the excellent injection of ink.
