The temperature of an accommodating room is adjusted without causing drop of melting water from an upper evaporator onto the accommodated food materials. A cold storage showcase includes a cooling circuit 50 in which an upper evaporator 40 provided on an upper side of an accommodating room 14 and a lower evaporator 42 provided on a lower side of the accommodating room 14 are connected to a cooling apparatus. The upper evaporator 40 and the lower evaporator 42 are connected in parallel with the cooling apparatus. An electromagnetic valve SV for supplying or interrupting circulation of a cooling medium in the lower evaporator 42 is provided halfway a second route R2 on an upstream side of the lower evaporator 42. During a cooling operation, the accommodating room 14 is cooled at all times by the upper evaporator 40. When temperature detecting means Th detects a drop in temperature of the accommodating room 14, the electromagnetic valve SV is closed to stop the cooling by the lower evaporator 42. On the other hand, when the temperature detecting means Th detects a rise in temperature of the accommodating room 14, the electromagnetic valve SV is opened to adjust the temperature by cooling the accommodating room 14 by the lower evaporator 42.
