A radiator grille, or ornament, includes a base material which transmits visible light and is made of an acrylic resin, a first ornamental layer coating the front surface of the base material, and a second ornamental layer coating the rear surface of the base material. The first and second ornamental layers each transmit visible light and have a thickness that is less than the wavelength of the visible light. It is preferred that the first ornamental layer and the second ornamental layer differ from each other in at least one of material, number of layers, thickness, refractive index of visible light, reflectance of visible light, absorptivity of visible light, and transmittance of visible light. The first ornamental layer is a hard coating layer, and the second ornamental layer is a hard coating layer or vapor deposition layer.

The invention claimed is: 1. An ornament, which is a component attached to the outer side of a vehicle and which inhibits viewing of structures behind the ornament from in front of the ornament, the ornament comprising: a base material which transmits visible light and is made of a synthetic resin; a first ornamental layer coating a front surface of the base material; and a second ornamental layer coating a rear surface of the base material, wherein the first and second ornamental layers each transmit visible light and have a thickness less than 800 nm, the second ornamental layer is formed by a dichroic vapor deposition or half mirror vapor deposition, an Abbe constant of the ornament is 60 or less, and the Abbe constant indicates the degree of color aberration resulting from the dispersion of light. 2. The ornament according to claim 1, wherein the first and second ornamental layers each have a thickness of 50 to 200 nm. 3. The ornament according to claim 1, wherein the first ornamental layer and the second ornamental layer differ from each other in at least one of material, number of layers, thickness, refractive index of visible light, reflectance of visible light, absorptivity of visible light, and transmittance of visible light. 4. The ornament according to claim 1, wherein the first ornamental layer has a light transmittance for visible light that is less than that of the second ornamental layer. 5. The ornament according to claim 1, wherein the first ornamental layer is formed by applying a hard coating agent on the surface of the base material. 6. The ornament according to claim 1, wherein the second ornamental layer is formed by alternately superimposing thin films of different types of metals. 7. The ornament according to claim 1, wherein the base material is acrylic resin. 8. The ornament according to claim 1, wherein the visible light is influenced by at least one effect selected from refraction, reflection, and interference in the first ornamental layer and influenced by at least one effect selected from refraction, reflection, and interference in the second ornamental layer. 9. The ornament according to claim 1 wherein the ornament is for a radiator grille. 10. The ornament according to claim 1, wherein the ornament provides a metallic gloss reflection when irradiated with visible light by a combination of optical properties of and arrangements between the base material and the first and second ornamental layers. 11. The ornament according to claim 10, wherein the metallic gloss reflection inhibits viewing structures behind the ornament from in front of the ornament. 12. An ornament, which is a component attached to the outer side of a vehicle an which inhibits viewing of structures behind the ornament from in front of the ornament, the ornament comprising: a base material which transmits visible light and is made of a synthetic resin; a first ornamental layer coating a front surface of the base material, the first ornamental layer transmitting visible light and having a thickness less than 800 nm; and a second ornamental layer coating a rear surface of the base material, the second ornamental layer transmitting visible light and having a thickness less than 800 nm, wherein the base material and first and second ornamental layers have optical properties and are arranged to provide a metallic gloss reflection when the ornament is irradiated with visible light, the second ornamental layer is formed by dichroic vapor deposition or half mirror vapor deposition. an Abbe constant of the ornament is 60 or less, and the Abbe constant indicates the degree of color aberration resulting from the dispersion of light. 13. The ornament according to claim 12, wherein the first and second ornamental layers each have a thickness of 50 to 200 nm. 14. The ornament according to claim 12, wherein the first ornamental layer and the second ornamental layer differ from each other in at least one of material, number of layers, thickness, refractive index of visible light, reflectance of visible light, absorptivity of visible light, and transmittance of visible light. 15. The ornament according to claim 12, wherein the first ornamental layer has a light transmittance for visible light that is less than that of the second ornamental layer. 16. The ornament according to claim 12, wherein the first ornamental layer is formed by applying a hard coating agent on the surface of the base material. 17. The ornament according to claim 12, wherein the second ornamental layer is formed by alternately superimposing thin films of different types of metals. 18. The ornament according to claim 12, wherein the metallic gloss reflection inhibits viewing structures behind the ornament from in front of the ornament,
