Abstract: A refrigerator of the present disclosure can include an ice making cell, a heater configured to supply heat to the ice making cell during an ice making process, and a controller configured to control the heater. The process for controlling the heater includes a basic heating process and an additional heating process that is performed after the basic heating process. In the basic heating process, the controller performs control so that a heating amount of the heater varies according to a mass per unit height of water in the ice making cell. In at least partial section of the additional heating process, the controller controls the heater to operate with a heating amount that is equal to or less than a heating amount of the heater in the basic heating process.
