Abstract
In a high-frequency heating device for driving a magnetron at a high frequency between 20 and 50 KHz, the magnetron is provided with a plurality of choke coils, each of which consists of a magnetic core having a sectional area between 40 to 70 mm.sup.2 and an electric wire around the magnetic core and having a diameter between 1.2 and 1.6 mm. In such a construction, the magnetron can be driven, using the high frequency with reduced thermal loss of the choke coil and restrained heat generation.
