To obtain a radio wave transmitting component for vehicles with which it is possible to reduce the amount of attenuation even when a radio wave is entered from any direction.SOLUTION: An ornament 10 includes a design unit 14 provided forward of a radar antenna 82 provided in a vehicle body and having a curved design surface 20 that is projected forward in the width direction. The thickness of the design unit 14 in the width direction has a maximum value at a position of L×tanθfrom an end to the inside in the width direction of the radar antenna 82 and has a minimum value at a middle position in the width direction of the radar antenna 82, where L represents the distance between the radar antenna 82 and the design unit 14 in the longitudinal direction and θrepresents the maximum emission angle of a radio wave in the radar antenna 82.SELECTED DRAWING: Figure 3 【課題】何れの方向から電波が入射されても減衰量を低減できる車両用電波透過部品を得る。【解決手段】オーナメント１０は、車体に設けられたレーダアンテナ８２の前方に設けられ、かつ幅方向において前方に凸となる湾曲状の意匠面２０を有する意匠部１４を備えている。幅方向における意匠部１４の厚さは、レーダアンテナ８２と意匠部１４との前後方向の距離をＬ、レーダアンテナ８２における電波の最大出射角度をθｍａｘとすると、レーダアンテナ８２の幅方向における端部から内側にＬ×ｔａｎθｍａｘの位置に極大値を有し、レーダアンテナ８２の幅方向中央の位置に極小値を有している。【選択図】図３
