METHOD OF PRODUCING LIQUID EJECTION HEAD

摘要

The present invention provides a method of producing a liquid ejection head, the method including the steps of preparing a substrate having a flow-path-wall member; bonding the flow-path-wall member to a resin layer that is composed of a photo-curing resin and serves as an ejection port member such that spaces serving as the flow paths are provided inside; providing through-holes in the resin layer such that the spaces communicate with the outside air; exposing part of the resin layer; heating the exposed portion of the resin layer; and removing the unexposed portion from the heated resin layer to form the ejection ports, thereby forming the ejection port member in the resin layer.
