Abstract
A high-frequency heating apparatus in which a waveguide having a rectangular terminating opening a.times.b is coupled with a heating chamber perpendicularly at the bottom wall thereby. The waveguide is excited in a TE.sub.0,n mode (n is any positive integer), and a turntable of dielectric material having a rotating center is located on a bisector between the crest (loop) and the valley (node) of this mode. A horizontal electric field is generated along the upper surface of the turntable, thereby strongly heating the center of the bottom surface of an article to be heated and improving the uniformity in heating of the article.
