Abstract: A refrigerator according to the present invention comprises: a storage space in which food is stored; a cooler for supplying cold to the storage space; a tray constituting an icing cell which is the space in which water is phase-changed to ice by the cold; a water supply unit for supplying water to the icing cell; a temperature sensor for detecting the temperature of water or ice inside the icing cell; a heater for supplying heat to the icing cell; and a control unit for controlling the heater. The control unit: performs controls so that the heater is turned on in at least a partial period while the cooler supplies the cold, and thus air bubbles disintegrating in water inside the icing cell move to liquid-phase water from a part where ice is generated, thereby enabling transparent ice to be generated; variably controls the heating amount of the heater so that the icing speed of water inside the icing cell in an icing step can be maintained within a predetermined range that is less than the icing speed when icing is performed with the heater turned off; and performs a defrosting step of defrosting and decreases the cooling amount of the cooler, when a defrosting start condition is satisfied in the icing step.
