There is provided a metal component having a novel planner pattern which differs from patterns obtained such as by printing, inscription, and a method for forming the metal component. A multi-face part (12') is provided on a half-finished product (10') which finally becomes a metal decorative button (10). The multi-face part (12') includes a plurality of small sectional faces (12", 13'a) and ridges (13b, 13'b) obtusely joining between two adjacent small sectional faces (12", 13'a). An outside of the half-finished product (10') including the multi-face part (12", 13'a) is plated. Then, the half-finished product (10') is barrel-polished. Thereby, the plating on portions corresponding to the small sectional faces (12", 13'a) remains and the plating on portions corresponding to the ridges (13b, 13'b) is removed, exposing the ground color of the half-finished product (10'). Then, the multi-face part is partially compressed to form the metal decorative button (10) having a compressed decorative surface (13). The compressed decorative surface (13) is given a pattern composed of a plurality of small sectional parts (12a) corresponding to the small sectional faces (12", 13'a) with the plating left and boundaries (12b) corresponding to the ridges (13b, 13'b) with the plating removed. |
