PROBLEM TO BE SOLVED: To provide a germanium medical device which is used to glue on the skin to mitigate a symptom of stiff shoulders, lumbagos, muscle pain or the like, wherein a plating layer of an alloy of copper and tin with excellent adhesion to germanium is formed as a bottom layer on a surface of a molding made of germanium as a main ingredient, a gold plating layer is formed as a connecting layer on the bottom layer, and a rhodium plating layer is formed on the connecting layer so that plating formation on the molding of germanium is made easier and controlling of various conditions of the production is made simpler to improve productivity. SOLUTION: The germanium medical device is constituted to have the plating layer of the alloy of copper and tin 3 with an excellent adhesion to germanium formed as the bottom layer on the surface of the molding 1 made of germanium as the main ingredient, the gold plating layer 4 on the bottom layer as the connecting layer and the rhodium plating layer 5 on the connecting layer as a decoration layer. Thereby the plating formation on the germanium molding 1 is made easier. COPYRIGHT: (C)2005,JPO&NCIPI
