A first groove is formed in a first main surface of a light guide member. A decorative layer is molded with the light guide member and provided on a second main surface of the light guide member. The decorative layer includes a first light-emitting portion that radiates the visible light emitted from a first light-emitting element from the light guide member and a second light-emitting portion that radiates the visible light emitted from the second light-emitting element from the light guide member. The first light absorbing member is disposed on a first groove bottom of the first groove, and has an absorptivity of visible light, which is higher than that of the light guide member. The first groove is positioned to block an optical path from the first light-emitting element toward a second region and an optical path from the second light-emitting element toward a first region.

A decorative sheet has a pattern formed with an interference pigment and is more versatile with reduced coloration specific to the interference pigment. A patterned layer has a pattern formed with an interference pigment to produce a color by interference of reflected light reflected after being incident as incident light on a front surface of the patterned layer. A front color-adjustment layer covers the front surface of the patterned layer and transmits the incident light, incident light, and the reflected light. A base film supports the patterned layer and the front color-adjustment layer. The front color-adjustment layer contains particles of a front absorbing pigment dispersed uniformly across the front color-adjustment layer. The front color-adjustment layer with the front absorbing pigment reduces a spectral component in a predetermined wavelength range of the incident light and the reflected light transmitted through the front color-adjustment layer.
