PURPOSE:To obtain a cooling storage box in which a storage chamber can be stably maintained at a predetermined humidity. CONSTITUTION:An atmosphere introduction passage 33 for communicating a storage chamber 8 with the atmosphere is formed. A chilled gas discharge passage 42 for communicating the high pressure part 7A of a chilled gas passage 7 with the atmosphere is formed. A humidifying blower 40 for forcibly discharging chilled gas in the part 7A from the passage 42 into the atmosphere upon operating at the time of humidifying the chamber 8 is provided. A damper 43 for opening/closing the passage 42 is provided. The damper 43 opens the passage 42 by the pressure upon operation of the blower 40 and closes the passage 42 at the time when the blower 40 is stopped. |
