Disclosed is an instrument illumination device enabling homogeneous illumination light in a broad area, without increasing the number of light sources, and thereby enhancing the freedom degree of the ornamental designing process. An instrument housing (12) includes a bottom face (12a) having LEDs (5, 5) disposed thereon and an illumination area (11) including a main illumination area (11a) having a main dial (8a) for displaying a revolution on the dial plate (16) covering a front opening and an auxiliary illumination area (11b) having an auxiliary dial (8b) for displaying water temperature. The main illumination area (11a) is in the shape of a ring having a cut-out at a lower part thereof, and the auxiliary illumination area (11b) fills the cut-out connecting the main illumination area (11a). Illumination light from the LEDs (5, 5) illuminates an entire face of the illumination area (11) in the ring shape from a rear side thereof as backlight. |
