ABSTRACT:
A process for producing an ink jet head comprises the steps of providing a substrate provided with a liquid discharge energy-generating portion, forming a photosensitive resin layer on the substrate, patterning the photosensitive resin layer into a liquid flow path pattern to form a solid layer for forming a liquid flow path on the substrate, covering the solid layer with a liquid flow path wall construction material composed of a curable resin on the substrate, curing the liquid flow path wall construction material, and removing the solid layer by dissolution to form a liquid flow path, wherein the liquid flow path wall construction material comprises an epoxy resin composition containing an epoxy addition-modified aromatic amine curing agent.
