To easily, inexpensively and reliably maintain internal humidity in a low-temperature storage for storing rice, vegetables, or the like.
A storage internal duct 6 comprises a water storage part, the storage part including a cold air discharge port and a cold air inlet port, and capable of storing drain water 18 dropped from a cooling chamber of a cooling unit 7; and an evaporation sheet provided on the cold air discharge port side of the water storage part, and the drain water 18 guided into the storage duct 6 is absorbed by the evaporation sheet 19. According to this, a storage chamber 2 can be surely humidified through a simple structure without increasing the dead space within the storage chamber 2.
