1. A vehicle exterior part configured to be applied to a vehicle including a millimeter wave radar device that transmits millimeter waves, wherein the vehicle exterior part is configured to be arranged frontward of the millimeter wave radar device with respect to a transmission direction of the millimeter waves, the vehicle exterior part comprising:
an ornamental body that is configured to decorate an exterior member of the vehicle;
a light source that emits light; and
a light diffuse reflection member that is millimeter wave-transmissive and diffuses and reflects the light,
wherein
the ornamental body includes:
a base that is millimeter wave-transmissive and diffuses and transmits the light; and
an ornamental layer that 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,
the light diffuse reflection member is arranged rearward from the ornamental body with respect to the transmission direction,
a peripheral edge of the ornamental body is joined with a peripheral edge of the light diffuse reflection member by an annular joining portion,
an area surrounded by the annular joining portion between the ornamental body and the light diffuse reflection member defines an accommodating portion, and
the light source is arranged in the accommodating portion, wherein
the ornamental body includes, in addition to the base, a light shield that blocks transmission of the light,
the light shield partially includes a peripheral light shield that contacts a peripheral edge of the base,
the peripheral light shield is welded in contact with the peripheral edge of the light diffuse reflection member, and
the peripheral light shield and the light diffuse reflection member are welded at the annular joining portion, wherein
the light shield includes an intermediate light shield surrounded by the peripheral light shield and located frontward of the base with respect to the transmission direction, and
a light reflector is arranged between the intermediate light shield and the base to reflect the light rearward with respect to the transmission direction.
