Patent ID: 8241540

Claim:
A method of manufacturing a liquid discharge head including a flow path member for forming a flow path communicating with a discharge port discharging a liquid, the method comprising the steps of: providing a mold of the flow path made of a positive photosensitive resin on a substrate; applying a coated layer on the mold for forming the flow path member, the coated layer including a solvent, an epoxy resin, and a curing agent of the epoxy resin; removing the solvent from the coated layer at a normal temperature under substantially 1 atm. so that the weight of the coated layer may become 93% or less of that of the coated layer at a time of the applying of the coated layer, and then further removing the solvent from the coated layer under a depressurized condition; curing the coated layer; and removing the mold to form the flow path.
