<p>A liquid ejection head includes a recording element substrate having a member with a liquid ejection orifice, and a substrate having an energy-generating element for ejecting the liquid; a wiring substrate including wirings connected to terminals that are formed along an end portion side of a surface of the substrate where the element is formed and are electrically connected to the element; and a support member including a support supporting the recording element substrate through adhesive, a groove formed along the support and a wiring support supporting the wiring substrate. A sealing material is applied to a connection portion between the terminals and wirings and is applied to a bottom surface of the groove formed on an end portion side of the surface where no terminal is formed. A part of a side of the substrate corresponding to the end portion side is exposed without being covered with the sealing material.</p> |
