PROBLEM TO BE SOLVED: To make a light guide body mounted to a vehicle uniformly emit light.SOLUTION: A light guide body 30 comprises a first light guide element 31, a second light guide element 32 and a third light guide element 33. The first light guide element 31 and the third light guide element 33 are formed of first mediums having first refractive indices. The second light guide element 32 has a second refractive index which is lower than the first refractive indices. A first incident face 31a and a second incident face 31b of the first light guide element 31 are arranged so that a part of light emitted from a light source 11 is made incident to the incident faces. A reflection face 31c of the first light guide element 31 is arranged so as to reflect light which is emitted from the light source 11, and made incident from the second incident face 31b. A first face 32a of the second light guide element 32 is arranged so that light which is made incident to the first incident face 31a and light which is reflected by the reflection face 31c pass therethrough. A second face 32b of the second light guide element 32 is arranged so that light which passes through the first face 32a passes therethrough, and includes a light dispersion element. The third light guide element 33 comprises an emission face 33a which is arranged so that light dispersed by the light dispersion element is emitted. |
