To provide an instrument device which provides novel, fine appearance, while reducing the number of components and assembly man-hours by using both a light source which delivers light to a light guide plate placed at the front of a dial and a light source which delivers light inside a light guide body placed at the rear of a pointer.

The instrument device comprises the dial 9, the light guide plate 10 placed at the front of the dial 9, the pointer 7 placed at the front of the light guide plate 10, the light-guiding body 11 place at the rear of the pointer 7, and a light-emitting diode 12 which is placed at the rear of the light-guiding body 11 and emits light to be delivered to the inside of the light-guiding body 11. The light-guiding body 11 is provided with a reflecting surface 24. The light of the light-emitting diode 12 is reflected by the reflecting surface 24, to be delivered to the inside of the light guide plate 10.
