To provide a drier of a heat pump type capable of restricting large-sizing, and achieving further higher efficiency.
This drier is provided with a heat pump unit in which a cooling medium circulates through a compressor 1, a heat radiator 2, a restrictor 3, and a vaporizer 4 in this order. Drying air heated by the heat radiator 2 is introduced to a subject 16, drying air extracting moisture from the subject 16 is cooled and dehumidified in the vaporizer 4, and it is then heated again by the heat radiator 2 to be reused as drying air. Drain water generated by dehumidification of drying air in the vaporizer 4 is dropped or atomized to the heat radiator 2, so that heat conductivity in the heat radiator 2 is accelerated by latent heat exchange with drying air and latent heat exchange with drain water conducted in the heat radiator 2. The heat radiator 2 can thus be made compact.
