摘要： 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.

摘要： A liquid ejection head is manufactured by forming a dent representing a substantially spherical profile so as to include a position for forming an ejection port on a surface of a photosensitive resin layer, then forming a latent image of the ejection port in the dent by an exposure treatment using a projection lens system, and developing the latent image. The center of the top surface of the latent image is shifted to the incoming side of the beam of exposure light from the lowest point of the dent.
