PROBLEM TO BE SOLVED: To provide a device and a method for remarkably excellent quick freezing that cause no cell destruction by completely eliminating a temperature equilibrium state and an approximate state in a maximum ice crystal generation temperature zone (0°C to -5°C). SOLUTION: The manufacturing method of a waterbearing frozen article immerses a waterbearing article 8 in a refrigerant liquid in a cooling and freezing tank 2, and in the liquid refrigerant, continuously or intermittently jets pressurized air or radiates an ultrasonic wave on the immersed waterbearing article 8 to quick-freeze it. The manufacturing device for a waterbearing frozen article has a structure wherein a conveyor 4 is disposed in the cooling and freezing tank 2 storing a refrigerant liquid, and a means for jetting pressurized air or radiating an ultrasonic wave on the waterbearing article 8 on the conveyor 4 in the refrigerant liquid 2 is disposed both over and under or either over or under the net conveyor 4.
