Zusammenfassung:	PROBLEM TO BE SOLVED: To restrain wrong detection on abnormality of quantity of stored water in an ice-making machine. SOLUTION: This ice-making machine includes an ice making chamber 12 for generating ice blocks, an ice making water tank 18 for storing water supplied from a water supply means 24 connected to an external water source, and an ice making water pump PM for supplying water from the ice making water tank 18 to the ice making chamber 12. The ice-making machine includes a rotational frequency detecting means for detecting that the ice making water pump PM reaches a preset rotational frequency, a clocking means for counting the elapse time from when the ice making water pump PM is driven until the rotational frequency detecting means detects the preset rotational frequency of the ice making water pump PM, and a determination means for determining abnormality on the abnormality of quantity of stored water in the ice making water tank 18 by comparing the preset setting time with the elapse time.
