Abstract
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 includes forming 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, which coated layer includes 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 thereof at a time of 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.
