Abstract
A heating device includes a high-frequency electrode embedded substantially in parallel with a heating surface of a ceramics base in the vicinity of the heating surface. A conducting hole toward this high-frequency electrode is formed in a back face of the ceramics base. This high-frequency electrode has a trapezoidal cone-like concave section toward the conducting hole at a region opposed to the conducting hole.
