A method of manufacturing a cryogenic regenerator includes the steps of supplying helium gas to a metallic helium gas sealing tube having a front end portion and a rear end portion that are open to replace air within the tube; sealing the rear end portion of the helium gas sealing tube; cooling the helium gas sealing tube and filling additional helium gas into the cooled helium gas sealing tube from a helium gas supplying unit; sealing the front end portion of the helium gas sealing tube after the helium gas sealing tube is filled with the additional helium gas; and winding the helium gas sealing tube into a coil structure around a core material to fabricate a helium gas sealing tube wound structure. |
