Abstract:
1. A method of manufacturing a liquid ejection head comprising an ejection port for ejecting a liquid and a flow path wall member constituting a flow path wall defining a flow path communicatively connected to the ejection port, the liquid ejection head manufacturing method comprising, in the following order: preparing a substrate having a flow path mold; arranging a first layer serving as the flow path wall member so as to cover the flow path mold; curing a portion of the first layer serving as a flow path sidewall; arranging a second layer so as to cover the cured portion of the first layer and the flow path mold; planarizing the second layer by pressing on the second layer toward the substrate; arranging the ejection port in the first layer and the second layer; and forming the flow path by removing the flow path mold.
