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 first cut off value from the surface shape, and a ratio of the wavelength Wsm when the amplitude Wc is 1 is 1:200 or more.

    【課題】樹脂成形品でありながら本物の金属を切削して製造されたような見栄えを均一な品質で得ることができる金属調加飾部品を提供する。【解決手段】加飾用金属調リング11は、合成樹脂により成形される基板本体20と、基板本体20の表面に被着される金属薄膜22と、を備える。金属薄膜22は、その表面形状から第1カットオフ値で得られたうねり曲線において、うねり波形の平均高さである振幅Wcと平均長さである波長Wsmの比率で捉えられて振幅Wcを1とした場合の波長Wsmの比率が1:600以上となる大きなうねりと、表面形状から第1カットオフ値よりも小さい第2カットオフ値で得られたうねり曲線において、うねり波形の平均高さである振幅Wcと平均長さである波長Wsmの比率で捉えられて振幅Wcを1とした場合の波長Wsmの比率が1:200以上となる小さなうねりと、を有する。【選択図】図1
