Abstract
A method for manufacturing a liquid discharge head including a flow path forming member to form a flow path communicating with a discharge port for discharging liquids includes forming an organic material layer on a substrate, applying a soluble resin on the organic material layer to form a resin layer, patterning the resin layer to form a pattern with a shape of the flow path, forming a cover layer as the flow path forming member on the pattern, forming the discharge port to expose a part of the pattern from the cover layer, eluting the pattern from the discharge port to form the flow path, irradiating a substance sticking to a surface of the flow path forming member on which the discharge port is formed with ultraviolet light, wherein the substance contains at least the organic material, and removing the sticking substance.
