Abstract
A dielectric heating device includes a first electrode and a second electrode that face an object to be heated and to which an AC voltage is applied, and a coil that is electrically coupled in series to the first electrode. A linear distance between one end and the other end of the coil is equal to or smaller than a linear distance between the one end and a central portion of the coil in a magnetic path direction of the coil.
