置。The main part of the back surface 10b is made of a transparent material such as an acrylic pedestal, and converts a part of the light from a substantially point light source 20 placed externally into substantially parallel light, and directly applies substantially white paint to the other part. The right end surface 10c is processed so that the light is incident on the right half of the back surface 10,b, and the surface is processed so that the light that has been converted into almost parallel light on the right end surface 10c is reflected and made to enter mainly the left half of the back surface 10,b. An illumination device having a processed left end surface 10d and having a structure in which light scattered by the back surface 10b is extracted as illumination light from a front surface 10a that is substantially parallel to the back surface 10b.
