PURPOSE:To carry out heating of the whole food material at a low temperature by using a vacuum pack prepared by vacuum sealing a food material and a specific thickness regulator, superposing the aforementioned thickness regulator on a thin part of the vacuum pack and carrying out irradiation with high-frequency electric waves. CONSTITUTION:A vacuum pack 1 containing a food material 3 vacuum sealed therein and a thickness regulator 6 prepared by sealing a readily mobile substance 4 (preferably a substance containing gelatin) in a vessel 5 composed of a film having flexibility are used. The aforementioned thickness regulator 6 is creased and then superposed on a thin part of the above-mentioned vacuum pack 1 so as to fit into a thick part of the vacuum pack 1 and wholly provide a uniform thickness. Irradiation and stop are repeated so as to afford the continuous high-frequency irradiation time within the range of 3+ or -0.75sec. Thereby, the objective heating is carried out.
