Abstract
An object of a high-frequency thawing apparatus is to uniformly thaw an entirety of an article with high efficiency and high-speed, particularly an article having a relatively large thickness. The apparatus is so constructed that a high-frequency power from a high-frequency generating circuit is supplied to a pair of opposing electrodes by way of an impedance matching circuit including a transformer to thaw an article (F) which is carried in between the opposing electrode pair by dielectric heating. The impedance matching circuit includes an electrostatic capacitor section (C) and an inductance section (L). A conductor each constituting the inductance section (L) has such a length that the downstream-located conductor with respect to the transport direction of a conveyor is longer than the upstream-located conductor.
