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.
