Document Type and Number:
Japanese Patent JP6000715
Kind Code:
B2
Abstract:
A manufacturing method of a liquid ejection head, which includes a step of preparing a substrate including a first layer, a step of forming a flow path mold for forming the flow path and a member located outside the mold with a gap between the mold and the member from the first layer, a step of providing a second layer so that the second layer fills the gap and covers the mold and the member located outside the mold with the gap between them, a step of forming an ejection orifice forming member for forming an ejection orifice from the second layer, a step of removing the member located outside the mold with the gap between them, and a step of forming a wall member located outside the ejection orifice forming member with at least a partial gap between the ejection orifice forming member and the wall member.
