HIGH-FREQUENCY HEATING DEVICE

PROBLEM TO BE SOLVED: To provide a high-frequency heating device with which it is possible to heat the surface and the content of the heated material without complicated operation, and quickly. SOLUTION: This device includes a rotating antenna 21 to be arranged in a heating room, and to be rotated within a prescribed face in order to disperse a high frequency wave in a waveguide, and furthermore, a metal plate arranged around the circumference of the rotating antenna in the heating room, and the heating room includes furthermore an antenna housing part to be connected to the waveguide, and to be arranged in the vicinity of the connected part to the waveguide in the heated room, and when the installation spacing, which is the spacing between the circumference of the rotating antenna and the face in the direction of intersecting the antenna housing part against a prescribed face, is not fixed, the metal plate is installed so as to be positioned at the longest part of the installation spacing.
