Provided is an automobile proximity warning system that notifies a detection object such as a pedestrian of automobile proximity while ensuring quiet for surrounding environment. A plurality of parametric speakers (13, 14, 15) are arranged so as to emit sound outside a vehicle from different positions of a vehicle body of an own vehicle. When a detection object existing around the own vehicle is detected by a sensor device, a distance detecting unit (5c) detects the direction and distance to the detection object, with the own vehicle being as a reference, from detection information from the sensor device. A warning control unit (5d) selects any of the speakers (13, 14, 15) for emitting sound in the direction and controls warning sound to be emitted while adjusting breadth of the directivity of the speaker in accordance with the distance.
