An object of the invention is to provide a vehicle approach notification sound generation device capable of generating a vehicle approach notification sound, by communication with another vehicle, that is different from that of said other vehicle. A vehicle approach notification sound generation device according to the invention comprises: a vehicle approach notification section that outputs a vehicle approach notification sound that gives notification of the approach of an ego vehicle; a vehicle approach notification sound acquisition section that acquires a vehicle approach notification sound that is output from another vehicle; a similarity distance calculation section that calculates the similarity distance of the vehicle approach notification sound of the ego vehicle, that is output from the vehicle approach notification section, and the vehicle approach notification sound of another vehicle, acquired by the vehicle approach notification sound acquisition section; a communication section capable of communication with the other vehicle; and a control section. The control section communicates with the other vehicle through the communication section and performs control to alter the vehicle approach notification sound of the ego vehicle in such a way as to adjust which of the other vehicle or the ego vehicle alters vehicle approach notification sound thereof. If the ego vehicle is to be the one that alters its vehicle approach notification sound, the vehicle approach notification sound of the ego vehicle is altered so that the similarity distance calculated by the similarity distance calculation section is at least a prescribed threshold value.
