    摘要: A method of manufacturing a liquid ejection head and a liquid ejection head capable of preventing corrosion of electrodes are provided. The method of manufacturing a liquid ejection head includes: a step of forming porous silicon areas in portions of a silicon substrate where the liquid paths are to be formed; a step of forming in layers in the porous silicon areas a protective layer, a heating resistor layer, an electrode layer and a heat accumulation layer; a step of forming ink ejection openings in the silicon substrate; and a step of removing the porous silicon areas.
