Abstract
Official abstract text for this publication.
A metallic decorative part for a vehicle display device includes: a substrate body molded from synthetic resin; a metal thin film formed of metal and deposited on a surface of the substrate body; and a mirror surface formed on a surface of the metal thin film in accordance with a surface shape of the substrate body. The mirror surface is formed such that, in a waviness curve obtained from the surface shape with a cutoff value defined as 250 μm, and in terms of a ratio between an amplitude as an average height of a waviness waveform and a wavelength as an average length of the waviness waveform, the ratio of the wavelength to the amplitude of 1 is equal to or greater than 600 and equal to or smaller than 6000, and mirror surface roughness is greater than 0 and equal to or smaller than 0.35 μm.

What is claimed is: 1. A metallic decorative part for a vehicle display device, the metallic decorative part comprising: a substrate body molded from synthetic resin; a metal thin film that is formed of metal and deposited on a surface of the substrate body; and a mirror surface that is formed on a surface of the metal thin film in accordance with a surface shape of the substrate body, wherein the mirror surface is formed such that, in a waviness curve obtained from the surface shape of the mirror surface with a cutoff value of 250 μm, a ratio of a wavelength to an amplitude, when the amplitude is 1, is equal to or greater than 600 and equal to or smaller than 6000, and mirror surface roughness of the mirror surface is greater than 0 and equal to or smaller than 0.35 μm, the amplitude being an average height of a waviness waveform in the waviness curve and the wavelength being an average length of the waviness waveform. 2. The metallic decorative part for a vehicle display device according to claim 1 , wherein the mirror surface is formed such that the ratio of the wavelength to the amplitude, when the amplitude is 1, is equal to or greater than 1000 and equal to or smaller than 6000, and the mirror surface roughness of the mirror surface is greater than 0 and equal to or smaller than 0.35 μm. 3. The metallic decorative part for a vehicle display device according to claim 2 , wherein the mirror surface is formed such that the ratio of the wavelength to the amplitude, when the amplitude is 1, is equal to or greater than 1400 and equal to or smaller than 6000, and the mirror surface roughness of the mirror surface is greater than 0 and equal to or smaller than 0.30 μm. 4. The metallic decorative part for a vehicle display device according to claim 1 , wherein the mirror surface is formed such that the ratio of the wavelength to the amplitude, when the amplitude is 1, is equal to or greater than 1400 and equal to or smaller than 6000, and the mirror surface roughness of the mirror surface is greater than 0 and equal to or smaller than 0.30 μm. 5. A vehicle display device, comprising: a display unit that displays information relating to a vehicle; a metallic decorative part for a vehicle display device that includes a substrate body molded from synthetic resin; a metal thin film that is formed of metal and deposited on a surface of the substrate body; and a mirror surface that is formed on a surface of the metal thin film in accordance with a surface shape of the substrate body, wherein the mirror surface is formed such that, in a waviness curve obtained from the surface shape of the mirror surface with a cutoff value of 250 μm, a ratio of a wavelength to an amplitude, when the amplitude is 1, is equal to or greater than 600 and equal to or smaller than 6000, and mirror surface roughness of the mirror surface is greater than 0 and equal to or smaller than 0.35 μm, the amplitude being an average height of a waviness waveform in the waviness curve and the wavelength being an average length of the waviness waveform.
