There is provided a vehicular rear and side warning device which does not issue a warning against a roadside stationary body such as a guard rail or a wall, and certainly issues a warning against a vehicle approaching from behind or a vehicle existing in a blind spot region of an own vehicle. A warning object judgment unit includes a noted sampling timing setting unit for setting a noted sampling timing on the basis of a peak timing obtained by a peak detection unit, and a frequency judgment unit for judging whether a frequency component not lower than a frequency threshold set by a frequency threshold setting unit exists with respect to an FFT operation result at the noted sampling timing. In a case where a front approaching body recognition unit judges that a material body approaches from in front of the own vehicle, and when the frequency judgment unit judges that a frequency component not lower than the frequency threshold exists, it is judged that the material body is a stationary body and is not a warning object.
