Zusammenfassung:	Safety and reliability are enhanced when the leakage of a refrigerant occurs, and ice-making efficiency is prevented from being lowered when a failure occurs in refrigerant detecting means. A refrigerant detection sensor S that can detect a refrigerant leaking from a refrigerating mechanism E transmits a detection signal to controlling means C when the refrigerant has been detected, and transmits a failure signal to the controlling means C when a failure has occurred in the refrigerant detection sensor itself. The controlling means C controls a cooling fan 34, which forcedly air-cools a condenser 31, to continuously operate and also controls an ice-making mechanism D to stop an ice-making operation and a deicing operation upon receiving the detection signal from the refrigerant detection sensor S. Further, the controlling means C controls the cooling fan 34 to continuously operate and also controls the ice-making mechanism D to continue the ice-making operation and the deicing operation upon receiving the failure signal from the refrigerant detection sensor S.
