A vehicle exterior part is configured to be arranged frontward of a millimeter wave radar device with respect to the transmission direction of millimeter waves. The vehicle exterior part includes an ornamental body, a light source that emits light, and a light diffuse reflection member. The light diffuse reflection member is millimeter wave-transmissive and diffuses and reflects light. The ornamental body includes a base and an ornamental layer. The base is millimeter wave-transmissive and diffuses and transmits the light. The ornamental layer is millimeter wave-transmissive and arranged frontward of the base with respect to the transmission direction. The light source, the ornamental body, and the light diffuse reflection member are arranged so that the light emitted from the light source is diffused and reflected by the light diffuse reflection member and directed toward the base.
