<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing an ink ejection head in which half-curing or curing of the position of a nozzle formation layer used as a nozzle hole is prevented, and which can prevent the generating of an inferior good in an ultraviolet irradiation process of photolithography. <P>SOLUTION: Since a resin which absorbs ultraviolet is impregnated into a space which is formed by a channel wall 53, and contains an ink heating element 52 so that the channel wall 53 is covered and a sacrifice layer 54 is formed by the resin, in an ultraviolet irradiation process, ultraviolet is absorbed by the sacrifice layer 54, it becomes possible to prevent the amount of ultraviolet reflected by a substrate 51, and the amount of ultraviolet irradiation applied to a nozzle formation layer 55 directly under a mask part 56a is prevented. Thereby, the half-curing or the curing of the position of the nozzle formation layer 55 used as a nozzle hole 55a is prevented, and the generating of an inferior good is prevented. <P>COPYRIGHT: (C)2012,JPO&INPIT |
