PROBLEM TO BE SOLVED: To provide a vehicular lighting fixture using a light guide body which forms no dark region and can emit light uniformly.SOLUTION: A vehicular lighting fixture 10 includes a light source 21 and a light guide body 30 which transmits light from the light source 21. The light guide body 30 includes: a first incident surface 31a arranged at a position facing the light emitting surface of the light source 21; a pair of second incident surfaces 31b which are arranged to face each other with the first incident surface 31a therebetween and on which the light from the light source 21 is incident; a pair of reflection surfaces 32 which are provided outside the second incident surfaces 31b as viewed from the first incident surface 31a and on which the light from the light source 21 is internally reflected; an emission surface 33 from which the light from the light source 21 is emitted; and a refraction part 34 which is provided between the second incident surfaces 31b and the emission surface 33 and refracts light L1 which is at least part of light incident on the first incident surface 31a so that the light L1 is close to parallel with light L2 reflected by the reflection surfaces 32 toward the emission surface 33. |
