Abstract
A liquid ejection head includes an element substrate having an energy-generating element configured to generate an energy for ejecting a liquid from an ejection orifice, a support member for supporting the element substrate, the support member including a liquid chamber formed therein to supply the liquid to the ejection orifice, and a damper portion for absorbing vibration of the liquid inside the liquid chamber, the damper portion being flexible. The support member has a through-hole for communicating with the liquid chamber at a position located above the liquid chamber in a vertical direction when the liquid ejection head is in a use orientation. The damper portion has a taper portion that tapers downwardly in the vertical direction and is positioned in such a manner that the tapering portion closes the through-hole, and the damper portion and the support member are attached to each other by a fixing member.
