An indicator lighting device in which light introduction efficiency into a indication portion can be improved, brightness is good and unevenness in lighting is small is provided; wherein an indicator 7 which has a translucent indication member (indication portion) 72 and a light introduction member (light introduction portion) 73 and is operated around an axis by a drive shaft 1 of a drive unit 2, light sources L which are disposed around the drive shaft 1 and illuminate the indication member 72 through the light introduction member 73 are provided, and the light introduction member 73 has a light receiving surface 73 a for receiving light from the light sources L, a first reflective surface 73 b for focusing light introduced from the light receiving surface 73 a to a position of a rotation axis V<SUB>a </SUB>of the drive shaft 1, a second reflective surface 73 c which is formed between the first reflective surface 73 b and the rotation axis and reflects light from the first reflective surface 73 b in a direction along the rotation axis V<SUB>a</SUB>, and a third reflective surface 73 d which is formed on the rotation axis V<SUB>a </SUB>in a way of facing the second reflective surface 73 c and reflects light from the second reflective surface 73 c in a longitudinal direction of the indication member 72.
