1. A radar device configured to emit radio waves and detects an object present in a prescribed detection region, the radar device comprising:
an antenna unit configured to emit the radio waves; and
a radio wave reflector that is disposed in a region around the antenna unit and outside the prescribed detection region and that includes a reflection surface disposed on an installation surface of the radar device, wherein:
the reflection surface includes a plurality of metal surfaces having heights that are different from each other with respect to the installation surface, the heights corresponding to a perpendicular distance away from the installation surface;
each metal surface of the plurality of metal surfaces is disposed to run lengthwise along a direction substantially perpendicular to the azimuth detection direction; and
the reflection surface is disposed such that an azimuth detection direction intersects with the reflection surface.
