A drying apparatus comprises a heat pump apparatus where a refrigerant is circulated through a compressor, a heat radiator, an expansion mechanism, and an evaporator, in that order. Drying air heated by the heat radiator is introduced to an object to be dried, the drying air that absorbed moisture from the object to be dried is cooled and dehumidified by the evaporator, and after that the air is heated again by the heat radiator for reuse as drying air.
