PROBLEM TO BE SOLVED: To provide a liquid ejection head that has high-printing speed without suppressing a head drive frequency while maintaining adhesion between a substrate and a flow channel forming member.SOLUTION: In the liquid ejection head, an intermediate layer is laid so as to avoid a part corresponding to a flow channel, thus a flow channel height can be sufficiently secured at the flow channel and a flow resistance is suppressed lower than the conventional flow resistance while maintaining adhesion between a substrate and a flow channel forming member. |
