A method of manufacturing a liquid discharge head including a flow path forming member configured to form a flow path communicating with a discharge port to discharge liquid, includes, providing a first layer which includes a photosensitive resin and a light absorption agent on a substrate, and providing a second layer which includes a positive photosensitive resin but substantially does not include the light absorption agent on the substrate, so as to coat the first layer, forming a pattern having a shape corresponding to the flow path by performing a patterning process, and providing a layer which becomes the flow path forming member on the substrate, so as to coat the pattern. The method further includes forming the discharge port by performing a patterning process including exposure of the layer that becomes the flow path forming member, and forming the flow path by removing the pattern.
