PROBLEM TO BE SOLVED: To provide a metal tone decorative component capable of achieving appearance which is similar to that obtained by cutting a real metal although it is a resin molding product, with uniform quality. ! SOLUTION: A metal tone decorative ring 11 comprises: a base material body 20 molded of a synthetic resin; and a metal thin film 22 which is deposited on a surface of the base material body 20. The metal thin film 22 comprises: large waves which are determined by a ratio between an amplitude Wc which is an average height of a waviness waveform and a wavelength Wsm which is an average length in a waviness curve obtained with a first cut off value from the surface shape, and the ratio of the wavelength Wsm when the amplitude Wc is 1 is 1: 600 or more, and small waves which are determined by a ratio between an amplitude Wc which is an average length of a waviness waveform and the wavelength Wsm which is an average length in a waviness curve obtained by a second cut off value smaller than the |
