An exterior vehicle component includes a proximity member disposed along
an outer perimeter of an electromagnetic wave transmission member
provided at a center of the component which is disposed in front of a
radar device. The proximity member includes a chromium-plated portion
formed on its front surface which reflects an electromagnetic wave. The
proximity member is formed of an acrylate-styrene-acrylonitrile resin or
a modified polyphenylene oxide resin having an attenuation coefficient
for electromagnetic wave transmission, which is equal to or greater than
a predetermined value.
