## Abstract

To realize a reduction in size of an electromagnetic wave heating system that utilizes water vapor. The electromagnetic wave heating system comprises a heat chamber having a first wall surface and a second wall surface different from the first wall surface, in which an object is placed to be heated, a flat antenna arranged on the first wall surface of the heat chamber and configured to emit an electromagnetic wave so as to heat an object inside the heating chamber, a discharger arranged on the second wall surface and configured to generate a discharge plasma by occurring a high voltage through a resonation structure of the electromagnetic wave, and an oscillator formed by a semiconductor element and configured to output the electromagnetic wave, and it is configured that the electromagnetic wave outputted from the oscillator is supplied into the flat antenna and the discharger.

## Claims
