<P>PROBLEM TO BE SOLVED: To manufacture a liquid ejection head that strikes a balance between improvement of flatness of an ejection port surface and protection of an electric circuit part on a substrate. <P>SOLUTION: A method for manufacturing the liquid ejection head includes steps of: preparing the substrate including a first layer; 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; 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 therebetween; forming an ejection port forming member for forming an ejection port, from the second layer; removing the member located outside the mold with the gap therebetween; and forming a wall member located outside the ejection port forming member with at least a partial gap between the ejection port forming member and the wall member. <P>COPYRIGHT: (C)2013,JPO&INPIT |
