To heat-finish a frozen dumpling stuffed with minced pork, etc., only with high frequency energy such that it is not watery and is nice-smelling with a crunching sound.
A food placement mesh composed of reception bars 8, 8,... made of a material having relatively high electric resistance such as nickelchrome and an outer periphery frame 7 is disposed in a heating chamber, and is supported with legs 9a, 9b, 9c formed integrally with the outer periphery frame 7 utilizing a wire material of the outer periphery frame 7. Thereupon, each leg 9a, 9b, 9c is connected with part of the reception bar, for example, the leg 9a is connected with the reception bars 8a, 8a to form a closed loop having a relatively long line length including the leg 9a, and heating of each loop is active compared with other parts. By heating the food placement mesh with a high frequency current upon high frequency heating a food particularly placed on the closed loop is heated with high frequency energy and heat produced from the food placement mesh.
