An instrumental device includes: a dial plate formed in a circular plate shape, and on which indexes indicating a condition of a mobile object are arranged in a circumferential direction of the dial plate; a case provided with a concave formed in a concave groove shape along the indexes, and to which the dial plate is attached so as to cover an opening of the concave; and a light source provided on a rear side of the dial plate in the concave opposite to the index, and emitting light toward the index. The case is provided with a light shield interposed between the index and the light source and facing the light source. At least a part of an outer periphery 36 of the light shield is formed in an arc shape so that a distance from an outer periphery of the concave is constant.
