省略する。 The trapezoidal metal plate 6a is the opening periphery 2 of the heating chamber 1.
It acts as a matching element that efficiently guides radio waves leaking through the gap between the door rear plate 4 and the radio wave attenuation cavity 7, thereby promoting the attenuation effect of the radio wave attenuation cavity 7. The details of the function and effect of the trapezoidal metal plate 6a are described in Japanese Patent Application No. 57-57115, and will therefore be omitted here.
