To provide a vehicular exterior component which can be thinned and also is suppressed from deteriorating in sensing performance.SOLUTION: A decorative component 10 comprises a design part 20 having a transparent layer 21 and a decorative layer 22, and a mounting part 30 that can be mounted on a vehicle 90. The mounting part 30 is arranged outside a radio wave irradiation area Ar of a milli-wave radar device 92. A back surface 27 at the milli-wave radar device 92 side of a radio wave transmission portion 26 of the design part 20 is smooth, and the thickness of the radio-wave transmission portion 26 is equal. This eliminates irregularities from the radio wave transmission portion 26, which can make the radio wave transmission portion 26 thinner because there are no places which are thick partially. Further, the thickness of the radio wave transmission portion 26 of the design part 20 alone is equal, which eliminates the necessity for arranging the other member in the milli-wave radar device 92 side with respect to the radio-wave transmission portion 26. This can reduce the thickness of the decorative component 10 as a whole, and can avoid deterioration in sensing performance due to detachment of a boundary between the design part 20 and the other member.SELECTED DRAWING: Figure 2

    【課題】薄型化でき、また検知性能の低下が抑制された車両用外装部品を提供する。【解決手段】装飾部品10は、透明層21および加飾層22を有する意匠部20と、車両90に取り付け可能な取付部30とを備える。取付部30は、ミリ波レーダー装置92の電波照射エリアArの外に配置されている。意匠部20の電波透過部26のミリ波レーダー装置92側の背面27は平滑であり、電波透過部26の肉厚は均一である。このようにして電波透過部26から凹凸を無くすことで、部分的に厚肉になる箇所が無い分だけ電波透過部26を薄型化できる。また、意匠部20単体で電波透過部26の肉厚が均一になっているので、電波透過部26に対してミリ波レーダー装置92側に他の部材を設ける必要がない。そのため、装飾部品10が全体として薄型化されるとともに、意匠部20と他の部材との境界の剥離に起因する検知性能の低下を回避できる。【選択図】図2
