PROBLEM TO BE SOLVED: To improve the energy-saving properties of an air supply device. SOLUTION: This air supply device is provided with a blower 1 supplying fresh air, a generator 3 driving this blower 1 and a heat exchanger 5 circulating the air supplied from the blower 1, and the heat exchanger 5 is provided with a heat exchange part 9 circulating the exhaust gas exhausted from the generator 3, so as to provide the air supply device with a space-heating function. The air supply device recovers the exhaust heat of the exhaust gas of the generator 3 to heat the air, and performs space heating with the air. Thus, the need for providing a heater or the like that is the air-heating means is eliminated, and the energy-saving properties of the air supply device can be improved for that.
