Abstract
A method of manufacturing a liquid discharge head provided with a liquid flow path communicating with a liquid discharge port on a substrate has a step of forming a first electrically conductive layer on the substrate, a step of forming a molding member into the pattern shape of the flow path on the substrate, a step of forming a second electrically conductive layer on the molding member so as not to contact with the first electrically conductive layer, a step of forming a metal film by a plating process around the molding member by the utilization of the first electrically conductive layer and the second electrically conductive layer, and a step of removing the molding member and forming the flow path.
