Provided is an illumination device which guides and projects projected light of LED elements (131) via light guiding bodies (110) which are configured from upper part light guiding bodies (111), middle part light guiding bodies (113), and lower part light guiding bodies (114). The upper part light guiding bodies (111) are hollow cylinders, and the LED elements (131) which project illumination light toward the partition wall inner parts of the upper part light guiding bodies are positioned on the upper end faces thereof. The middle light guiding bodies (113) have flaring hollow shapes which are bent such that the illumination light which is projected and proceeds nearly linearly from the LED elements (131) along the partition wall inner parts of the upper part light guiding bodies (111) is blocked, and to widen in the outer circumference direction of the upper part light guiding bodies. The lower part light guiding bodies (114) have hollow flange shapes extending in a nearly horizontal direction so as to be orthogonal to the upper part light guiding bodies (111). |
