A water-circulating type ice maker of the present invention comprises a refrigerating capacity detecting means for detecting the refrigerating capacity of the ice maker at a set temperature, which is slightly above the temperature where the ice-making water starts to freeze in the state of partial ice, and an ice-making plate temperature lowering means for lowering the temperature of the ice-making plate as a counter measure against partial ice generation so that the ice-making plate temperature lowering means starts operating when the refrigerating capacity detected by the refrigerating capacity detecting means is lower than a predetermined capacity. The comparison of the refrigerating capacity detected by the refrigerating capacity detecting means and the predetermined capacity can be made by detecting the high side pressure, the low side pressure, the condensing temperature or the evaporating temperature when the ice-making water reaches the set temperature. Furthermore, the ice-making plate temperature lowering means can be one that ,for example, stops the ice-making water circulation pump.
