Original Abstract Submitted

An object is to provide a liquid ejection head capable of improving reliability of the connection section between an element substrate and an electrical wiring substrate. The liquid ejection head ejecting liquid includes an element substrate having a terminal and a wiring substrate including a wiring portion connected to the terminal in contact therewith. In a direction perpendicular to a surface on which the terminal is provided on the element substrate, a second distance between the end portion of the element substrate and the wiring portion is greater than a first distance between the surface on which the terminal is provided and a portion opposite to the terminal of the wiring portion.
