Claim 19:
20. A refrigerator comprising:
a cabinet defining a storage space; and
an ice maker disposed in the storage space, wherein the ice maker comprises:
a tray body made of a flexible material, the tray body comprising a plurality of chamber walls configured to define a plurality of ice chambers arranged along a central line extending in a first direction and passing through centers of the plurality of ice chambers;
a first heater disposed at the plurality of chamber walls, the first heater being configured to supply heat to the plurality of ice chambers during an ice-making process; and
a second heater that surrounds the plurality of chamber walls and is spaced apart from the first heater, the second heater being configured to supply heat to the plurality of ice chambers during an ice-separation process after the ice-making process,
wherein a first radial distance from one of the centers to the first heater is less than a second radial distance from the one of the centers to the second heater, and
wherein the first heater is configured to, based on heating the plurality of ice chambers during the ice-making process, cause bubbles in water received in the plurality of ice chambers to be collected at a portion of each of the plurality of ice chambers.
