Abstract
An emblem (30) (vehicle decorative part) includes a decorative main body (31) and a heater (55). The decorative main body (31) is configured to be attached to a vehicle at a front side in a transmission direction of millimeter waves from a millimeter wave radar to decorate the vehicle and has a millimeter wave transparency. The heater (55) has a heating element (57) that emits heat when energized. At least a part of the heating element (57) is located in a irradiation region (Z1) of the millimeter waves in the heater (55). As a millimeter wave attenuation reducing configuration that reduces attenuation of the millimeter waves passing through the heater (55), the heating element (57) is incorporated in the heater (55) in a condition where an area proportion of an area of a section of the heating element (57) that occupies the irradiation region (Z1) to an area of the irradiation region (Z1) is set such that an attenuation amount of the millimeter waves is less than or equal to a permissible value.
