A light guide device that performs uniform brightness transmitted light illumination regardless of a distance from an incident portion is provided. Light that is emitted from a light source, and enters from an incident portion of a light guide member (light guide body) made of a translucent member formed along an outer edge portion of a decorated portion, travels in the light guide portion while repeating total reflection by an inner surface of the light guide member. In the light-guiding portion, the light is guided in the decorated portion made of a translucent member from the inside of the light guide member, and is emitted outside by being scattered by the inside of the decorated portion, and in the non-light-guiding portion, the light that travels in the light guide member is prevented from traveling in the decorated portion.
