液体喷出头及其制造方法
摘要：
一种液体喷出头及其制造方法。提供一种在防止打印头中的基板与流路形成构件之间的剥离的同时简化打印头的制造过程并且降低制造成本的打印头及其制造方法。在本发明的打印头中，在热产生部(2)中的流路形成构件侧的部分形成保护层。保护层(20)含有贵金属。于是，在保护层(20)中的流路形成构件侧的部分，除了与热产生部(2)对应的部分之外，表面由贵金属的氧化物制成，而在保护层(20)中的流路形成构件侧的与热产生部(2)对应的部分中，表面由贵金属制成。
摘要（英）：

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.
