摘要： A liquid ejection head includes a liquid ejection board and a liquid ejection head component disposed on the liquid ejection board. The liquid ejection board includes a substrate, an energy generating device on the substrate, a channel defining member defining a liquid channel and having a liquid ejection opening in communication with the liquid channel, a liquid supply passage in communication with the liquid channel, a liquid supply opening in communication with the liquid supply passage and having a smaller opening cross-sectional area taken in a direction perpendicular to a flow direction of a liquid than the liquid supply passage, and an opening in communication with the liquid channel. The liquid channel allows a liquid to be in contact with the energy generating device. The liquid ejection opening allows a liquid to be ejected therethrough. The liquid ejection head component closes at least a portion of the opening.

摘要： A liquid ejection head includes a substrate having an energy generating element arranged therein and an ejection port forming member laid as superposed above the substrate. At least one ejection port is formed so as to run through the ejection port forming member. The ejection port forming member has a concave portion including the ejection port formed therein on the surface thereof opposite to the surface thereof facing the substrate, and has a convex portion on the surface of the ejection port forming member facing the substrate so as to correspond to the concave portion.

摘要： A method for manufacturing a liquid ejection head includes the steps of: preparing a substrate including an energy-generating element disposed on a first surface of the substrate and a supply path for liquid; disposing a dry film on the first surface of the substrate in such a manner that the dry film partially enters the supply path; etching the dry film from a side of the dry film facing the first surface of the substrate so that the dry film has an etched surface substantially in parallel with the first surface and covers the supply path; forming a resin layer to be a flow path member on the dry film covering the supply path; and removing the dry film covering the supply path.
