ABSTRACT:
A method for manufacturing an ink discharge port of an ink jet recording head, which is provided with the ink discharge port for discharging an ink liquid droplet for adhesion thereof to a recording medium, a liquid chamber for retaining ink to be supplied to the discharge port, an ink flow path communicating with the discharge port and the liquid chamber, an energy generating element provided for a part of the ink flow path, and an ink supply port for supplying ink from outside to the liquid chamber, includes the step of processing and forming the wall face inside the ink discharge surface of the ink discharge port to a surface condition having irregularities of greater than or equal to 0.3 micrometer and less than or equal to 1 micrometer as the standard deviation value for the surface roughness thereof.
