ABSTRACT:
The present invention provides a method of producing a liquid ejection head having a solution guide member protruding on a head substrate. The solution guide member has a sharp-pointed portion protruding from a liquid surface of a flowing solution in which charged particles are dispersed. The solution guide member guides the solution to the sharp-pointed portion such that the solution is ejected from the sharp-pointed portion by an electrostatic force. The method comprises the steps of forming a photosensitive resin layer on the head substrate; molding a convex portion having the sharp-pointed portion on a surface of the formed photosensitive resin layer by pressing a mold member against the surface of the photosensitive resin layer; and exposing a region of the molded convex portion; and developing the exposed photosensitive resin layer to produce the solution guide member provided on the head substrate.
