A producing method of a liquid discharging head includes a discharge port discharging a liquid and a flow path communicating with the discharge port, the method comprising the steps of forming a pattern of a shape of the flow path on a substrate, forming a layer of a negative type photosensitive resin composition including a photo-initiated polymerization initiator on the substrate so as to coat the pattern, at least a region of the layer in a vicinity of the substrate including a sensitizing agent of the photo-initiated polymerization initiator, a density of the sensitizing agent in the layer formed to be higher in the region than in a part where the discharge port is formed, forming the discharge port by exposing the layer to pattern the layer, and removing a pattern to form the flow path.
