Microwave heating apparatus.

摘要

A microwave heating apparatus is provided with a waveguide (33), a heating chamber (22) and a plurality of power feeding ports (31, 32, 36, 37) for communicating the waveguide and the heating chamber, and is adapted to oscillate radio waves so as to uniformly heat a material to be heated in the heating chamber (22) by arranging a microwave oscillating antenna (44) along the surface of the waveguide facing the segment or portion between the plurality of power feeding ports (31, 32, 36, 37).
