Claims

[Scope of utility model registration request]

A heating chamber 3 that houses an object to be heated 6, a high frequency oscillator 1 that supplies high frequency energy into the heating chamber 3, and a part of the high frequency energy from the high frequency oscillator 1 to the object to be heated 6.
In a high-frequency heating device that includes a receiving antenna 7 that extracts a signal corresponding to a temperature change in dielectric loss, and controls the oscillation of a high-frequency oscillator 1 using the signal, a saucer 5 made of a dielectric material on which an object to be heated 6 is placed. A receiving antenna 7 is embedded inside the receiving antenna 7, one end 7a of which protrudes from the side surface of the saucer 5, and one end 7a of the saucer 5 is thickly molded around one end 7a.
A high-frequency heating device characterized in that a receiving signal is connected to an attenuator 8 made of a metal tube 8c fixed to the outer wall of the heating chamber 3, and a received signal is extracted to the outside of the heating chamber 3.
