The illumination device includes a substrate provided with a light emitting element on a surface of the substrate, a cover member that forms a part of an outer surface of the steering wheel and has light transmission of emitting visible light output from the light emitting element to an outside of the steering wheel, a light guiding member configured to guide the visible light output from the light emitting element to the cover member, and a base member to which the substrate and the cover member are attached and which holds the substrate and the cover member. The light guiding member is held by being sandwiched between the substrate and the base member.",
