PROBLEM TO BE SOLVED: To provide a stirling cooling device with high reliability for operation and an extended operation life capable of reducing the power consumption and suppressing the reduction in humidity of a cooling space. SOLUTION: This stirling cooling device has a stirling refrigerator 1, a cooling circuit 10 connected to the low-temperature part 3 of the refrigerator 1, a radiation means 6 mounted on the high-temperature part 2 of the refrigerator 1 to carry and radiate the heat of the high-temperature part 2, a plurality of evaporators 8 and 9, and one or more valves 12 (16a and 16b). A condenser 7 and the evaporators 8 and 9 provided in the cooling circuit are mutually connected so that the evaporators 8 and 9 are arranged in parallel, and the temperature of the low-temperature part 3 of the refrigerator 1 is controlled according to the opening and closing state of the valves 12 (16a and 16b).
