PROBLEM TO BE SOLVED: To uniformly heat in a short time. SOLUTION: This thawing box comprises a magnetron 2, a stirrer fan 5 for stirring microwaves in a heating box 1, a stirrer position detector 9 for detecting the position of the stirrer fan 5, a heating pattern memorizing device 10 for memorizing temperature rise rates at heated material positions corresponding to the position of the stirrer fan 5, and a driving device control circuit 13 for fully adjusting the rotation rate of the stirrer fan 5 and the oscillation of the magnetron 2 on the basis of the signals of the heating pattern memorizing device 10 and the temperature rise rates memorized in the heating pattern memorizing device 10.
