PROBLEM TO BE SOLVED: To provide a forming method of electric wiring which can form a predetermined electric wiring accurately on the side surface of base material having a solid form or on base material having irregularities. SOLUTION: This method contains a first process wherein a first thin film layer 400 and a second thin film layer 401 which turn to electric conduction parts are formed on base material, and sequentially a metal thin film capable of anodic oxidation, as a third thin film layer 310, is formed on the second thin film layer 401, a second process wherein a notch 351 is formed in a thin film layer 300 composed of the three layers 400, 401, 310, and the thin film is divided into a part 330 to be turned into electric wiring and a part 331 to be eliminated, a third process wherein a barrier type anodic oxidation layer 301 is formed by anodizing the surface of the part 331 to be eliminated, and a process which selectively eliminates the part 331 to be eliminated. The above processes are performed in this order and wiring 201 is formed. |
