A presence notification system generates a notification sound around a vehicle with a quiet running sound, such as a hybrid car, an electric automobile, or a fuel-cell automobile, and notifies pedestrians of presence and approaching of the vehicle so as to be capable of heightening safety, and can maintain comfortability in the vehicle without bringing discomfort to the surrounding pedestrians and a driver and a fellow passenger in the vehicle. A contact pickup device 3 for capturing oscillation of a housing of an inverter I so as to convert the oscillation into an electric signal is mounted to the housing of the inverter I to be used in a driving circuit for driving an electric motor M. An amplifying device 5 for amplifying the electric signal output from the contact pickup device 3 is provided, and a notification sound generating device 2 for outputting a sound to a periphery of the vehicle based on the electric signal output from the amplifying device 5 is provided. |
