A low-temperature drying apparatus 10 includes a furnace body 12, a sheet 20, an infrared light transmitting plate 30, a supply device 40, a discharge device 45, and infrared heaters 50. The sheet 20 holds a coating film 22, which is an object to be dried, so that the coating film 22 is placed in the furnace body 12. The infrared light transmitting plate 30 is provided on a surface of the furnace body 12 that faces the sheet 20. The supply device 40 and the discharge device 45 generate a cooling flow in a space between the coating film 22 and the infrared light transmitting plate 30. The infrared heaters 50 are disposed to face the infrared light transmitting plate 30 in the open space OP outside the furnace body 12.
