Abstract

PURPOSE:To shorten the length of a choke cavity section by providing rectangular and plate-shaped resonant plates perpendicular to the extension line connecting the center lines of heaters and parallel with the axes and located on the bottom side of a box body in the box body forming the outer hull of a structure body for seed heaters constituting a device. CONSTITUTION:The high-frequency energy generated by a high-frequency oscillator 4 passes through a wave guide 3 and is radiated into a heating chamber 1 through a high-frequency feed port 2 to induction-heat the hood 5. On the other hand, seed heaters 6 provided on the ceiling section of the heating chamber 1 apply singes to the hood 5. A choke structure body 8 is provided on the outer periphery of terminals 7 of the heaters 6 penetrating the side wall face of the heating chamber 1 in this constitution. Resonant plates 12 are provided at preset positions in a choke cavity 11, the capacity component is increased, the high-frequency transmission passage 14 is apparently extended, and the external leakage of the microwave energy is prevented even if the length of the passage 14 is shorter than 1/4 wavelength.
