PROBLEM TO BE SOLVED: To provide a vehicle decorative part that features snow-melting capability and minimizes attenuation of a millimeter wave transmitting through a heater section thereof.SOLUTION: An emblem (vehicle decorative part) 30 comprises a main decorative body 31 and a heater section 55. The main decorative body 31 is attached to a vehicle at a position in front of a millimeter wave radar device in a millimeter wave transmission direction to decorate the vehicle, and has a millimeter wave transmissivity. The heater section 55 has a heat generator 57 that generates heat when energized. At least a portion of the heat generator 57 is located in a millimeter wave irradiation area Z1 within the heater section 55. As a millimeter wave attenuation minimization aspect for minimizing attenuation of a millimeter wave transmitting through the heater section 55, an area ratio of the heat generator 57 in the irradiation area Z1 to the irradiation area Z1 is set to keep millimeter wave attenuation at a level no greater than a tolerance when incorporating the heat generator 57 in the heater section 55.SELECTED DRAWING: Figure 2

    【課題】融雪機能を発揮しつつ、ミリ波がヒータ部を透過する際の減衰を抑制する。【解決手段】エンブレム30(車両用装飾部品)は、装飾本体部31及びヒータ部55を備える。装飾本体部31は、車両において、ミリ波レーダ装置からのミリ波の送信方向の前方に取付けられて、車両を装飾するとともに、ミリ波透過性を有している。ヒータ部55は、通電により発熱する発熱体57を有している。発熱体57の少なくとも一部は、ヒータ部55におけるミリ波の照射領域Z1内に配置されている。発熱体57は、ミリ波がヒータ部55を透過する際の減衰を抑制するミリ波減衰抑制態様として、上記照射領域Z1内における発熱体57の同照射領域Z1に占める面積比率を、ミリ波の減衰量が許容値以下となるように設定した状態でヒータ部55に組込まれている。【選択図】図2
