The appearance of an illumination unit, in which a light source is mounted on a transparent substrate, when turned on can be improved. The following structures are formed. A first half mirror is disposed on a front side of the transparent substrate on which a plurality of the light sources are mounted, and a half mirror is disposed on a rear side of the transparent substrate. Light emitted from each light source is repeatedly reflected between the first half minor and the minor while being transmitted through the transparent substrate, so as to be output forward from the first half minor. Thus when the illumination unit which is turned on is observed from the outside, the light which is reflected multiple times between the first half minor and the minor causes an image of the light source to look as if a number of shining images of light sources are aligned in a front-and-rear direction. On the other hand, when the illumination unit which is not turned on is observed from the outside, the transparent substrate and the plurality of light sources are invisible due to the first half minor.
