Abstract
Provided is a method of manufacturing a liquid ejection head having an element which generates energy utilized for ejecting liquid and an electrode layer electrically connecting the element. The method includes the steps of: providing an electrode layer on a substrate, a width of one portion of the electrode layer being smaller than that of another portion near the one portion; providing a resist layer on a part of the electrode layer by a screen printing method or a dispense method in such a manner that an end of the resist layer is positioned at the one portion; providing another layer on another part excluding the part of the electrode layer by utilizing the resist layer as a mask; and removing the resist layer.
