Abstract: 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.
