A heat radiating structure of an interior member is provided with a heat
radiating portion adapted to be applied to a vehicle and disposed on a
rear surface of an interior member whose surface is adapted to be applied
with external energy, a heat receiving and radiating portion connected to
a vehicle body of the vehicle, and a reflecting member allowing heat
radiation, radiating from the heat radiating portion to an inside of the
interior member, to be reflected and propagated to the heat receiving and
radiating portion. The reflecting member cooperates with the heat
radiating portion and the heat receiving and radiating portion to define a
closed space.
