Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an illumination structure of an instrument, which can increase degree-of-freedom of a formation on a front surface side by illumination light, while preventing electric leakage from a wire and obtaining excellent space efficiency.SOLUTION: A liquid crystal backlight illumination device 16 is separately provided on a liquid crystal display device 14, and multiple LED light-emitting bodies arranged in a vehicle width direction at predetermined intervals are mounted on a back surface side 6b of a circuit board 6. On a back surface side of a liquid crystal glass part 14a, a rectangular flat plate-like light-emitting surface part 18a arranged parallel to the liquid crystal glass part 14a and a leg part 18b extending toward the LED light-emitting bodies so as to be integrated with the light-emitting surface part 18a along a lower edge part 18e of the light-emitting surface part 18a are provided so that a substantially L-shaped light guiding member 18 when viewed from a lateral view is obtained. Illumination light of the LED light-emitting bodies is guided by the light guiding member 18, and planar light-emitting backlight illumination having the substantially uniform amount of light can be obtained.
