Claim 17:
18. A refrigerator comprising:
a storage chamber;
a cooler configured to supply cold air;
a tray configured to form a cell, which is configured to form a space in which liquid is phase-changed into ice;
a temperature sensor provided in the tray;
a heater configured to supply heat to the cell; and
a controller configured to control the heater to operate during an ice making process according to a first heating process and a second heating process after the first heating process, wherein the first heating process comprises a plurality of processes,
the controller is configured to control the heater such that a heating amount of at least one process of the plurality of processes increases or decreases in response to a change in a heat transfer amount of the cold air and liquid in the tray;
wherein, in at least a partial section of the second heating process, the controller is configured to control the heater such that a heating amount of the heater is equal to or less than a heating amount of the heater in the first heating process.
