INSTRUMENT DEVICE

PROBLEM TO BE SOLVED: To provide an instrument device which allows a contour part and a notification part to be efficiently illuminated with one and the same light guide body, even having an illumination chamber between an indicating needle and a contour part.SOLUTION: An instrument device comprises an indication part including calibrations to be pointed by an indicating needle 60, a notification part which is located on the opposite side of the indication part with reference to the indicating needle and notifies predetermined information, a contour part which surrounds the notification part, the indicating needle, and the indication part and exhibits the contour of the instrument, and an instrument board which is located behind the indicating needle. The instrument device further comprises a first light source 57 and a second light source 58 which emit light beams, a circuit board 50 which is located behind the instrument board so as to be opposite to the instrument board, a light guide body 80 which receives the light beam emitted from the first light source so as to guide the received light beam to the indication part and the contour part, and a light guide body case 70 which is arranged between the circuit board and the instrument board so as to house the light guide body.
