PROBLEM TO BE SOLVED: To provide a snowfall machine which achieves higher snow making capacity. SOLUTION: The snow-making machine has an air-supplying device for supplying compressed air, a water-supplying device for supplying water, a pipe for transferring air, and a pipe for transferring water. In the vicinity of a slope, a plurality of air hydrants 7, connected to the pipe for transferring air and a plurality of water hydrants 8 connected to the pipe for transferring water, are installed along the slope. An artificial snow-feed part constituted of a cooler/ dehumidifier 9, a snow gun 11 and hoses 12, 13 and 14 is mounted detachably on the air hydrants 7 and the water hydrants 8. The cooler/dehumidifier 9 is constituted of a filter 91, a dehumidifying device 92 installed at the rear stage of the filter 91, a cooling device 90 installed at the rear stage of the dehumidifying device 92, pipes 88, 98 and 99, and a valve 89 and installed between the snow gun 11 and the air hydrants 7.
