To provide an instrument device with which it is possible to suppress unevenness in luminance of an illuminated member as much as possible.SOLUTION: An instrument device comprises: a panel body 10 having a light transmitting unit 11 and a light scattering unit 14; a plurality of light sources 30 disposed on a circuit board 20; a case member 40 for accommodating the light sources 30; an instrument housing arranged on a viewer side of the panel body 10; and a light reflection member for reflecting emission light emitted from the light transmitting unit 11 toward the instrument housing. The case member 40 includes a light diffraction unit 44 for diffracting illumination light in a plurality of directions in a prescribed direction X and a reflection unit 45 for reflecting the light diffracted in the plurality of directions toward the light transmitting unit 11, the light diffraction unit 44 and the reflection unit 45 being alternately arranged in the prescribed direction X, the light sources 30 being disposed on the circuit board 20 so as to correspond to the light diffraction unit 44, with a recess 44d provided in a counter-face region 44c of the light diffraction unit 44 that faces the light scattering unit 14.SELECTED DRAWING: Figure 4

    【課題】被照明部材の輝度ムラを極力、抑制することが可能な計器装置を提供する。【解決手段】光透過部11と光拡散部14とを有するパネル体10と、回路基板20に配設される複数個の光源30と、光源30を収容するケース部材40と、パネル体10の視認者側に配置される計器ハウジングと、光透過部11から出射される出射光を計器ハウジングに向けて反射する光反射部材とを備え、ケース部材40は、照明光を所定方向Xに沿う複数方向に分光させる分光部44と、当該複数方向に分光した光を光透過部11に向けて反射する反射部45とを有し、分光部44と反射部45とが所定方向Xに沿い交互に配置されるとともに分光部44に対応するように回路基板20に光源30が配設され、分光部44の光拡散部14との対向領域44cに窪み部44dが設けられている。【選択図】図4
