A radar device includes: plural unit antennas, each including plural antenna elements configured to transmit or receive a radio wave, the plural antenna elements being aligned in a predetermined direction in a plane and connected by a transmission line. The plural unit antennas include a first unit antenna having plural antenna elements arranged asymmetrically with respect to a virtual straight line parallel to the predetermined direction, the virtual straight line passing through an antenna phase center of the first unit antenna, and a second unit antenna having plural antenna elements arranged asymmetrically with respect to a virtual straight line parallel to the predetermined direction passing through an antenna phase center of the second unit antenna. The plural antenna elements of the second unit antenna are arranged in a manner substantially symmetrical to the plural antenna elements of the first unit antenna with respect to the virtual straight line.
