An ambient information notification apparatus includes: an interior sound acquisition device acquiring an interior sound in a compartment of the vehicle; an ambient information presentation sound generator generating an ambient information presentation sound; and an ambient information presentation sound output device outputting the ambient information presentation sound. The ambient information presentation sound satisfies that a sound pressure level of the ambient information presentation sound is higher than the interior sound in a predetermined frequency band, and is lower than or equal to the interior sound in other frequency band, and that the ambient information presentation sound is provided by stereophony, in which a sound image localization direction approximately directs to a virtual sound source.
