Summary:PROBLEM TO BE SOLVED: To provide a method for manufacturing an inkjet recording head especially whose mechanical strength of circumference of a nozzle surface, especially outlet port has been improved while having desirable functions for nozzle material such as patterning characteristic, adhesion, etc. SOLUTION: The method of manufacturing a liquid discharging head includes (1) the process for preparing a photo-curing resin composition containing inorganic particles on a substrate provided with an energy generating element and forming a layer used as a nozzle member, (2) the process for exposing the first outlet port pattern to the layer used as the nozzle member, (3) the process for exposing the second outlet port pattern to the layer used as the nozzle member, and (4) the process for forming the nozzle member and the outlet port by developing, in order of the above. The outlet port configurations in the first and second outlet port patterns are an analogue with the same central point, and the outlet port area of the second outlet port pattern is smaller than the one of the first outlet port pattern.
