Abstract: The present invention relates to a refrigerator having a defrosting device, the refrigerator comprising: a refrigerator main body; an evaporator provided in the refrigerator main body; a defrosting heater provided at the lower side of the evaporator so as to emit heat when a power source is applied; and a heat pipe for transferring heat to the evaporator, one side of the heat pipe being arranged so as to be able to transfer heat to one side of the defrosting heater, and the other side of the heater pipe extending to the upper side along the vertical direction of the evaporator. Thereby, the present invention can shorten defrosting time and reduce power consumption.
