Abstract
A vehicle decorative part includes a decorative main body and a heater. The decorative main body is configured to be attached to a vehicle at a front side in a transmission direction of millimeter waves from a millimeter wave radar and has a millimeter wave transparency. The heater has a heating element that emits heat when energized. At least a part of the heating element is located in an irradiation region of the millimeter waves in the heater. As a millimeter wave attenuation reducing configuration that reduces attenuation of the millimeter waves passing through the heater, the heating element is incorporated in the heater in a condition where an area proportion of an area of a section of the heating element that occupies the irradiation region to an area of the irradiation region is set such that an attenuation amount of the millimeter waves is less than or equal to a permissible value.
