Abstract
A ceramic heater body is formed in a plate shape, and has electrode attaching portions at both ends of the heater body. A plurality of openings are formed in the electrode attaching portion, and a metallized layer is formed on the inner peripheral surface of each of the openings. Electrodes having a plurality of wires are connected to the electrode attaching portions, for supplying power to the heater body. The metal wires are inserted into the openings formed having the metallized layers on the inner peripheral surfaces, and are secured by brazing to the metallized layers. The diameter of the metal wire is set to 0.5 to 3 mm, and the metal wires are buried in the openings, at a depth of 1 to 5 mm.
