Patent ID: 8133662

Claim:
A method for manufacturing a liquid discharge head that includes a flow path wall member which forms a wall of a flow path communicating with a discharge port for discharging a liquid and a substrate which forms the flow path in contact with the flow path wall member, the method comprising: providing a first layer, which is made of a photosensitive resin on the substrate, for forming a pattern having a shape of the flow path; providing a second layer which is capable of absorbing light within a photosensitive wavelength range of the photosensitive resin and has a shape corresponding to the shape of the flow path, on the first layer so as to come into contact with the first layer; performing patterning of the first layer which includes exposure of the first layer with the light using the second layer as a mask, and forming the pattern from the first layer; providing a cover layer which is made of a photosensitive resin and serves as the flow path wall member so as to cover the second layer and the pattern; forming the discharge port on the cover layer by performing patterning of the cover layer which includes exposure of the cover layer with the light; and forming the flow path by removing the second layer and the pattern.
