PROBLEM TO BE SOLVED: To suppress a rod-like light guide body receiving thermal damage through an incident surface.SOLUTION: A vehicular lighting fixture 10 includes: a transparent rod-like light guide body 11 having an incident surface 12 of light at an end surface; and a light source 13 arranged in a state of being opposed to the incident surface 12 of the rod-like light guide body 11, and for generating heat to equal to or higher than a softening point of the rod-like light guide body 11. The vehicular lighting fixture 10 makes the light emitted by the light source 13 incident from the incident surface 12 to the rod-like light guide body 11, and makes the rod-like light guide body 11 emit light in a linear manner. In this vehicular lighting fixture 10, a transparent heat insulation part 18 is arranged between the light source 13 and the incident surface 12 of the rod-like light guide body 11. |
