A vehicle proximity notification apparatus has first and second loudspeakers which output warning sound notifying proximity of a vehicle to an outside, and an adjusting unit. The adjusting unit adjusts the sound output from the first loudspeaker so that a sound collecting signal, which is obtained when the second loudspeaker collects the sound output from the first loudspeaker, coincides with a reference signal, in a state in which the first loudspeaker functions as a sound outputting element and the second loudspeaker functions as a sound collecting element. In addition, the adjusting unit adjusts the sound output from the second loudspeaker so that a sound collecting signal, which is obtained when the first loudspeaker collects the sound output from the second loudspeaker, coincides with a reference signal, in a state in which the second loudspeaker functions as a sound outputting element and the first loudspeaker functions as the sound collecting element.
