The purpose of the present invention is to provide a vehicle approach notification sound generation device capable of efficiently generating a vehicle approach notification sound to pedestrians present on the side of the road. This vehicle approach notification sound generation device (1) is provided with a vehicle-external speaker (11) which outputs in a first direction a first vehicle approach notification sound for notifying of the approach of the vehicle, a vehicle-external speaker (13) which outputs in a second direction a second vehicle approach notification sound for notifying of the approach of the vehicle, a travelled road attribute inference unit which infers road attributes, i.e., attributes of the road travelled by the vehicle, a travelled lane detection unit (6) which infers the lane travelled by the vehicle, and a total control unit (7) which, on the basis of the road attributes inferred by the travelled road attribute inference unit and the lane inferred by the travelled lane inference unit, controls output of the first vehicle approach notification sound and second vehicle approach notification sound.
