PROBLEM TO BE SOLVED: To prevent point lighting and to improve uniformity of brightness on an emission surface of a light guide body.SOLUTION: A lighting fixture 1 for a vehicle includes: a light source 31 arranged so as to be directed to a first radial direction with a front-and-back direction being an axial direction; and a light guide body 40 for guiding the light emitted by the light source 31 and emitting it frontward. The light guide body 40 has: an incident part 41 facing the light source 31 and taking in the light emitted by the light source 31 as parallel light; a first light guide part 43 for guiding the parallel light in the first radial direction; a reflection surface 45 formed on the opposite side of the incident part 41, reflecting the light guided by the first light guide part 43 in a second radial direction and diffusing the reflection light to the front-and-back direction; a second light guide part 47 extending in the second radial direction from the reflection surface 45 and guiding the light reflected by the reflection surface 45 into the second radial direction; and an emission surface 48 formed on a front surface of the second light guide part 47 and emitting the light guided by the second light guide part 47 frontward. |
