The present disclosure provides a vehicle illuminating device including a lamp housing that functions as a heat sink, a light emitting element disposed in the lamp housing, and a control board that controls the light emitting element. A protruding portion is formed to have an internal space in the lamp housing, and at least a part of the control board is disposed in the internal space. Since the light emitting element is disposed in the lamp housing functioning as a heat sink, and at least a part of the control board is disposed in the internal space of the protruding portion, heat generated in the light emitting element and heat generated in the control board hardly affect each other, and the generation positions of the heat are apart from each other.
