Zusammenfassung:	PROBLEM TO BE SOLVED: To thaw ice flowing to a circulating passage from a heat storage tank with a simple structure and improve the efficiency of ice making operation. SOLUTION: An ice making device is provided with a refrigerant circulating circuit and a water circulating circuit B. In the ice making device, water taken out of a heat storage tank T by driving a pump P is supercooled by a supercooling heat exchanger 42, and ice nucleus formed in an ice nucleus forming device 46 is mixed into the water to cancel a supercooling state and make ice. The ice making device is provided with a preheater 40 for heating water in the downstream side of the pump P and a return pipeline for returning half of water supplied from the preheater 40 to the upstream side of the pump P.
