To provide a print head that simplifies the manufacture process of a print head and reduces the manufacturing cost while preventing the peeling-off between a substrate and a flow passage forming member in the print head, and a method of manufacturing the print head. In the print head of the present invention, a protective layer is formed in a flow passage forming member side portion in a heat generating portion 2. The protective layer 20 contains a noble metal. Then, in the flow passage forming member side portion in the protective layer 20, the surface thereof is made of an oxide of a noble metal except in a portion corresponding to the heat generating portion 2, while in the portion corresponding to the heat generating portion 2 on the flow passage forming member side in the protective layer 20, the surface thereof is made of the noble metal.
