A vehicle presence notification apparatus notifying a presence of a vehicle includes an alarm device and a dynamic speaker. The alarm device includes an alarm generator generating an alarm sound and an acoustic tube through which the alarm sound is emitted outside of the vehicle. The dynamic speaker generates a notification sound with audible frequency. The dynamic speaker is fixed to the acoustic tube and emits the notification sound inside of the acoustic tube, such that the notification sound is generated outside of the vehicle through the acoustic tube.
