A vehicle approach notification device (120) is provided with speakers (121A, 121B) for outputting warning sounds to give external notification of the approach of a vehicle, and an adjustment unit (123). When the speaker (121A) is being made to function as a sound output element and the speaker (121B) is being made to function as a sound pickup element, the adjustment unit (123) adjusts the sound outputted from the speaker (121A) so that a sound pickup signal (145A), obtained due to the sound outputted from the speaker (121A) being picked up by the speaker (121B), matches a reference signal (146A). When the speaker (121B) is being made to function as a sound output element and the speaker (121A) is being made to function as a sound pickup element, the adjustment unit (123) adjusts the sound outputted from the speaker (121B) so that a sound pickup signal, obtained due to the sound outputted from the speaker (121B) being picked up by the speaker (121A), matches a reference signal.
