PROBLEM TO BE SOLVED: To provide an indicator illumination device constituted so as to efficiently guide the light incident on the light receiving part of a light guide body from a light source to an indicator to more brightly illuminate the indicator. SOLUTION: The indicator illumination device has an indicator 3, and a plane part 13 and a bent part 14 both of which guide the light of the light source 6 to the indicator 3, and the light guide body 5 provided with a first reflecting surface 15 is provided between the plane part 13 and the bent part 14. The bent part 14 consists of a light receiving part 16, a second reflecting surface 17 for reflecting the light incident on the light receiving part 16, and a light guide part 18 for guiding the light reflected from the second reflecting surface 17 to the first reflecting surface 15. The second reflecting surface 17 and the light receiving part 16 form an arcuate cross section rotated around the base line being the light source axis X passing the light source 6.
