Abstract
There is provided a method of manufacturing a liquid discharge head having a substrate including energy generating elements, and a discharge port member, which is provided with discharge ports and is joined to the substrate, thereby forming liquid flow paths communicating with the discharge ports. The method includes, in the following order, preparing a conductive base on which a first insulating resist and a second insulating resist for forming the discharge ports are stacked in this order; performing plating using the first resist and the second resist as masks, and forming a first plated layer; removing the second resist; performing plating on the base using the first resist as a mask, thereby forming a second plated layer so as to cover the first plated layer; removing the base and the first resist, thereby forming the discharge port member; and joining together the substrate and the discharge port member.
