An object of the invention is to provide a vehicle approach notification sound generation device capable of generating a vehicle approach notification sound in an appropriate range in accordance with vehicle speed. A vehicle approach notification sound generating device (1) according to the invention is characterised in that it comprises: a vehicle speed calculation section (3) that calculates vehicle speed; vehicle-external speakers (8, 9, 10) that output vehicle approach notification sound that gives notification of the approach of a vehicle; and an overall control section (4) that controls the direction of orientation of the vehicle approach notification sound or the angular width of orientation, indicating the spread of directionality of the vehicle approach notification sound. This overall control section (4) controls the direction of orientation or the angular width of orientation in accordance with the speed calculated by the vehicle speed calculation section (3).
