PROBLEM TO BE SOLVED: To provide a flow-down ice-making machine capable of reducing adhesion of scale and improving reliability of an ice-making completion detection signal. SOLUTION: An outlet 42, which is opened below an ice-making completion level of ice-making water in an ice-making water tank 20, and a suction port of a circulation pump 22 are connected together via a suction pipe 44. A bypass pipe 48 is arranged to be inserted into the ice-making water tank 20 so that a suction port 50 of the bypass pipe 48 is arranged at the ice-making completion water level, while a discharge port 52 of the bypass pipe 48 is connected to a midpoint of the suction pipe 44. A flow rate sensor 54 detecting a flow rate of ice-making water passing through the bypass pipe 48 is arranged in a midpoint of the bypass pipe 48. In ice-making operation, when the flow rate sensor 54 detects a flow rate 0 of the ice-making water, a control means 56 stops the circulation pump 22, and the ice-making operation is completed.
