| 1. A method of manufacturing an ink jet recording head including a substrate equipped with an energy generating element for
generating energy to discharge ink and a supply port for supplying the ink to the energy generating element, a discharge port
for discharging the ink, and a flow path forming member for forming a flow path for allowing communication between the discharge
port and the supply port, said method comprising the steps of:
providing an adhesive material for forming an adhesive layer on the substrate;
providing a photosensitive material containing a photosensitive resin on the adhesive material, and performing exposure and
development to form a side wall forming member for forming a side wall of the flow path;
patterning the adhesive material using the side wall forming member as masks to form the adhesive layer;
placing a ceiling layer on the side wall forming member, the ceiling layer being a part of the flow path forming member; and
forming the discharge port in the ceiling layer.
