A radar apparatus mounted in a vehicle includes an inward bent surface and a radar device. The inward bent surface is formed in a lower portion of a bumper of the vehicle, and curves inward with a higher degree of curvature in a horizontal plane than a bumper surface of an upper portion of the inward bent surface. The radar device is placed behind the inward bent surface so that a beam axis of the radar device penetrates the inward bent surface.
