摘要： On the liquid ejection head substrate, an upper protective layer, as well as coming into contact with the resin layer which configures a path forming member such as a ejection opening, comes into contact with ink in an heat generating portion inside the channel formed. The upper protective layer contains iridium and silicon. The upper protective layer is configured so that, at a surface in contact with the ink and resin layer, Ir100-xSix attains a 15 at. %≦X≦30 at. % silicon content rate, and that X more becomes zero as a position in the upper protective layer more approaches an adhesion layer. As a result, at the interface where the upper protective layer comes into contact with the path forming member, by the silicon attaining the heretofore described content rate, it is possible to improve the adhesion with the path forming member made of resin compared with a case of using iridium alone.
