PROBLEM TO BE SOLVED: To provide a refrigerator capable of preventing the rise of a surface temperature of a glass tube even when a single glass tube is used in a radiant heater, and increasing an internal volume of the refrigerator by miniaturizing a cooling unit. SOLUTION: In this refrigerator comprising a cooler 13 composed of a refrigerant tube and a plurality of fins, an electrically heated winding 9 provided with a cover radiant 12 on its upper portion, the radiant heater 8 composed of the glass tube 10 and a cap 11, and a half-wave rectified defrosting circuit 15, and using a combustible refrigerant, the rise of the surface temperature of the glass tube can be prevented even when the defrosting heater using the inexpensive single tube as the glass tube of the radiant heater, is applied, by half-wave rectifying the input of the radiant heater, further cooling performance of high efficiency can be achieved by applying an efficient constitution of a cooling air trunk hardly disturbing the cooling flow channel, and a space can be effectively utilized by miniaturizing the cooling unit.
