PROBLEM TO BE SOLVED: To provide a freezing method comprising subjecting material to be frozen such as food or a living body to frozen storage without causing cell destruction: and to provide a freezing device where material to be frozen such as food or a living body is subjected to frozen storage. SOLUTION: The freezing device is provided with a cooling means 21 cooling the material to be frozen, a means impressing electric field on the material to be frozen (electrodes 3, 3), and a control means 20 controlling alternating voltage to be applied on the cooling means 21 and the electrodes 3, 3. In the device, a supercooling process where the electric field is impressed on the material to be frozen while cooling the material to be frozen, and a freezing process where the impression of the electric field is stopped after finishing the supercooling process.
