Abstract: High frequency heating device is provided with heater disposed adjacent to mount base on which object to be heated is mounted and having a plurality of surface wave transmission lines electrically isolated from each other, and first and second high frequency power generators, each of which generates high frequency power having different frequency. Surface wave transmission lines receive at least one of the high frequency power generated by first high frequency power generator and the high frequency power generated by second high frequency power generator. According to this aspect, interference between the high frequency powers is not occurred and electromagnetic field coupling is not occurred. As a result, in the high frequency heating device provided with the surface wave transmission line using a periodic structure, uneven baking caused by the electromagnetic field coupling can be suppressed, and a heating state of an object to be heated can be easily controlled.
