PROBLEM TO BE SOLVED: To provide a flow-down type ice maker capable of promoting falling of an ice mass, without generating strain on an ice making surface. SOLUTION: A pair of ice making plates 12 and 12 are oppositely arranged by sandwiching an evaporation pipe 14 for circularly supplying a refrigerant. A plurality of vertical ribs 16 are separately formed in the width direction on the ice making plates 12. An ice making area is defined between the vertical ribs 16 and 16 opposed in the width direction. Projections 18 separately projecting to the ice making area side in the vertical direction, are formed in an extension part 16a for constituting the vertical ribs 16. The ice mass generated in the ice making area quickly falls, by separating from the ice making surface 12a by running on the projections 18 and 18, when a freezing part with the ice making surface 12a melts and falls in an ice removing process. Since the projections 18 are formed in the extension part 16a, processing strain is not generated on the ice making surface 12a, and adverse influence such as reducing ice making capacity is not caused.
