<P>PROBLEM TO BE SOLVED: To achieve a refrigerating machine having high cooling performance and stable quality by securely preventing entry of molten solder to a cooling storage medium and a high temperature side heat exchanger, enabling easy determination of treatment conditions of brazing and reducing heat inflow to a cooling storage device, during brazing of the pulse tube refrigerating machine. Ž<P>SOLUTION: After one end of a cooling storage tube and the high temperature side heat exchanger are jointed to each other by perimeter welding, brazing of a radiator and the cooling storage device and high temperature side heat exchanger is performed. Since the cooling storage medium is arranged outside the radiator, heat inflow from the radiator to the cooling storage device is reduced. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
