The present invention provides a freezer capable of preventing/restraining quality of foods from being deteriorated, freezing method, and frozen objects manufactured using the freezer and freezing method. The freezer 10 comprises a freezer main body 101 , a cluster fragmenting device 1 A for fragmenting water clusters contained in the objects 5 , a loading part 7 for loading the objects 5 , a heat exchanger 8 and a cold gas supply device. The cold gas supply device comprises a dehumidifying device 11 for dehumidifying a cold gas heat-exchanged by the heat exchanger 8 , and a fan 9 for-circulating dehumidified cold gas to maintain the inside of the freezer 101 in a dry state. Further, the cluster fragmenting device 1 A includes plural magnetic field generating devices 2 that imparts magnetic fields to the objects 5 containing water and changes the strength of magnetic fields with time elapsed.
