The wiring line is constructed of a laminated structure of a refractory metal, a low resistance metal and a refractory metal, and the wiring line is further protected with an anodized film. As a result, it is possible to form the wiring line having the low resistance and the high heat resistance and to form a contact with an upper line easily.
