PROBLEM TO BE SOLVED: To prevent the adsorption of impurities to a transfer tube. SOLUTION: This recondenser comprises a refrigerating machine comprising at least one cooling stage, a condensing container incorporating a condensation heat exchanger thermally connected to the cooling stage, a heat-insulating vacuum container receiving the condensing container, the transfer tube for introducing a refrigerant condensed by the condensing container to a refrigerant storage container, a vacuum cylinder connected to the heat-insulating vacuum container and covering an outer periphery of the transfer tube, an evaporative gas introducing pipe connected to an electric current introducing portion of the refrigerant storage container and collecting an evaporative gas, a compressor connected to the evaporative gas introducing pipe and rising a pressure of the evaporative gas, and a pressure pipe for introducing the gas of which the pressure is risen by the compressor, to the condensing container.
