The refrigerator may include: one or more main doors open and closed, while sealing a storage room of the refrigerator, and having convenience space and a dispenser provided therein; sub-doors open and closed, while sealing the convenience space, and connected to the main doors; and an ice making room connected to one side main door to supply water or ice to the dispenser.

Abstract: Proposed is an ice maker disposed in a refrigerator to provide ice to an ice bucket. The ice maker may include a tray configured to be filled with water and positioned in the ice maker to freeze the water to make ice, the tray includes a high thermal conductive composite material configured to emit heat in response to an electric current supplied thereto; a tray cap connected to top of the tray to reduce an area of top of the tray so that the water filled in the tray is prevented from overflowing because of the inertia generated by the movement of the tray; a frame assembly connected to the tray; electrodes connected to both sides of the tray, respectively; and a motor connected to the tray to rotate the tray so that the ice is separated from the tray by gravity.
