PROBLEM TO BE SOLVED: To save on power, to prolong the service life, and to suppress noise of a water feed pump while maintaining an excellent sanitary state of water in an ice-making device. SOLUTION: In an ice-making device having a water feed pump to automatically feed water (S12) to an ice-making tray from a water feed tank every time when ice produced in the ice-making tray is discharged (S20), a water feed pump is turned to the reverse side (S22) when a predetermined time is elapsed to the next water feed (Y side of S16) after water is fed by the water feed pump. In addition, by switching each water feed time SMORTOR by the water feed pump in a case of feeding water for the first time after the water feed pump is driven in the reverse direction and in the other case (S15 and S23), the water feed time is switched according to whether or not water is filled in a water feed passage from the water feed tank to the ice-making tray, and water of the predetermined quantity is constantly fed to the ice-making tray.
