To provide a superconductor cooling device that can cool a coolant liquid to a supercooling temperature without wasting a coolant gas and can be reduced in size, and a superconductor cooling method.SOLUTION: A superconductor cooling device has: a refrigerator (50) that cools a first coolant; a super-cooler (51) having a storage part (52) for the first coolant and a heat exchange part (53) for heat exchange between the first coolant cooled by the refrigerator and a second coolant, wherein the storage part (52) for the first coolant is reduced in pressure to below the atmospheric pressure; and a superconductor cooling line (104) in which the heat exchange part (53) of the super-cooler (51) and a superconductor cooling part (54) are disposed and the second coolant circulates. There is also provided a superconductor cooling method using the same.SELECTED DRAWING: Figure 1 【課題】冷媒ガスを浪費せず、冷媒液を過冷却温度まで冷却でき、かつ小型化できる、超電導体の冷却装置及び超電導体の冷却方法の提供。【解決手段】第一の冷媒を冷却する冷凍機（５０）と、前記第一の冷媒の収容部（５２）及び前記冷凍機で冷却された前記第一の冷媒と第二の冷媒との熱交換を行う熱交換部（５３）を備え、前記第一の冷媒の収容部（５２）が大気圧未満に減圧されている過冷却器（５１）と、前記過冷却器（５１）の前記熱交換部（５３）及び超電導体の冷却部（５４）が配置され、前記第二の冷媒が循環する超電導体冷却ライン（１０４）と、を備える超電導体の冷却装置並びにこれを用いる超電導体の冷却方法。【選択図】図１
