An evaporator for an ice maker includes an evaporator body having a refrigerant flow path formed therein; a dipping member connected to the evaporator body, for a refrigerant having a temperature lower than a freezing point of water to flow in the refrigerant flow path to generate ice in a state in which at least a portion of the dipping member is submerged in water; a heater having at least a portion inserted into the refrigerant flow path, and directly or indirectly heating at least one of the refrigerant in the refrigerant flow path, the evaporator body, and the dipping member to separate the ice generated on the dipping member from the dipping member; and a connection member connecting the evaporator body and the refrigerant flow path to be connected to a refrigeration cycle, and inserting the at least a portion of the heater into the refrigerant flow path.
