Zusammenfassung:	The invention relates to a radar device. The radar device is configured to be provided with an antenna unit (3) for transmitting and receiving a radar wave, a high-frequency circuit unit (4) for handling a high-frequency signal, and a low-frequency circuit unit (2) for handling a low-frequency signal. The low-frequency circuit unit (2) is disposed on a main surface of a main printed circuit board (6). The high-frequency circuit unit (4) and the antenna unit (3) are disposed on a first surface and a second surface of a sub printed circuit board (7), respectively. The sub printed circuit board (7) is mounted in a space not occupied by the low-frequency circuit unit (2) on the main surface of the main printed circuit board (6). As a result, the high-frequency signal can be used by using an insulating material required to suppress dielectric loss only for the sub printed circuit board (7).
