PROBLEM TO BE SOLVED: To provide a light light alloy wheel capable of easily and inexpensively preventing the lowering of a yield before forming a metal thin film layer and amending a coating. SOLUTION: This bright light alloy wheel is constituted by forming a bed layer, the metal thin film layer and a clear layer on the metal thin film layer, and an intermediate layer is characterized by being formed between the bed layer and the metal thin film layer. It is desirable to form the intermediate layer in a thickness of more than 5μm and less than 100μm and to use a coating material containing no pigment. COPYRIGHT: (C)2008,JPO&INPIT
