PROBLEM TO BE SOLVED: To provide a cooling apparatus for cooling a cooled object in an electromagnetic field or a state where an electric field is generated, in which the object can be efficiently kept in a super-cooling state.SOLUTION: A cooling device includes: a freezer for cooling a cooled object； an electromagnetic wave irradiator for generating an electromagnetic field that acts on the object, in which an intensity of the electromagnetic field is variable； a control part which controls an operation of the freezer and the electromagnetic wave irradiator, the control part performing a super-cooling operation for cooling the object in the freezer while generating the electromagnetic field； and a temperature sensor for measuring a temperature of the object. During the super-cooling operation, the control part adjusts the intensity of the electromagnetic field generated by the electromagnetic wave irradiator on the basis of the temperature measured by the temperature sensor.SELECTED DRAWING: Figure 5【課題】電磁場又は電場を作用させた状態で被冷却物を冷却する冷却装置であって、効率よく物品の過冷却状態を作り出すことが可能な冷却装置を提供する。【解決手段】冷却装置は、被冷却物を冷却する冷凍機と、被冷却物に作用させる電磁場を発生させる、電磁場の強度が可変な電磁波照射器と、冷凍機及び電磁波照射器の動作を制御し、電磁場を発生させた状態で、冷凍機で被冷却物を冷却する過冷却運転を行う制御部と、被冷却物の温度を計測する温度センサと、を備える。制御部は、過冷却運転中に、温度センサにより計測された温度に基づいて、電磁波照射器が発生させる電磁場の強度を調整する。【選択図】図５
