Abstract
A heating device includes an electrode embedded near the heating surface of the ceramic base substantially in parallel to the heating surface. In the rear surface of the ceramic base, a terminal hole extending toward the electrode is formed. Between the bottom surface of the terminal hole and electrode, a conductive ceramic member is embedded and connected to the electrode. The conductive ceramic member has a thermal expansion coefficient equal to that of the ceramic base. The electrode and terminal are electrically connected through the conductive ceramic member.
