PROBLEM TO BE SOLVED: To provide a freezing detection apparatus capable of discriminating whether a liquid to be a freezing detection target is frozen or not independent of conductivity of the liquid to be a freezing detection target.SOLUTION: A freezing detection apparatus, when a temperature detected by a temperature detection part 150 arranged in the vicinity of an ice making pipe 120 is varied due to a flow of a cooling liquid 111 in a liquid tank 110, determines that no ice is formed around a tip portion of the temperature detection part 150, and when the temperature detected by the temperature detection part 150 is not varied, determines that ice is formed around the tip portion of the temperature detection part 150. |
