PROBLEM TO BE SOLVED: To provide ice of high degree of transparency, in an automatic ice- making machine for a refrigerator. SOLUTION: The automatic ice-making machine 10 is equipped with an ice-making tray 13 which is axially supported rotatably, with an upper side opened and is sectioned into a plurality of small chambers inside by a central partitioning part 47 in the direction of the axis of rotation, a feed water pump which feeds water to the ice-making tray 13 through one feed water pipe and a driving device 11, which rotates the ice-making tray 13 to invert it vertically for release of ice, after an ice-making process in the tray 13 is ended. The central partitioning part 47 is provided with a notch groove and the feed water pump feeds water to the tray 13, divided into portions for a plurality number times, while the driving device 11 swings the tray 13, so that the water may flow through the notch groove, until the water fed to the tray 13 is frozen after the start of water feeding to the tray 13 by the feed water pump.
