Provided is a high-frequency dielectric heating device for which fine adjustment of inductance is achieved easily and with high precision, while reducing device cost and simplifying device structure. A high-frequency dielectric heating device (10) comprising a high-frequency power source (20), a pair of electrodes (30) disposed facing each other, a reflected power detection means for detecting reflected power occurring due to heating of a substance to be heated, the reflected power detection means being connected between the electrodes (30) and the high-frequency power source (20), and an inductance matching device (40) for adjusting the reflected power, wherein the matching device (40) is provided with a capacitor (C1) connected in parallel to the high-frequency power source (20), and a capacitor (C2) and/or coil (L) with which it is possible to adjust at least reactance, the capacitor (C2) and/or coil (L) being connected in series to the electrodes (30), the high-frequency power source (20) being configured such that frequency can be varied. |
