Abstract

A heating device of the present invention has a heating element of a substantially V-shape and is made of a ceramic material having electric conductivity. Electrode plates are respectively mounted at both ends of the heating element for energizing the heating element. Further, the heating device has a holder for holding the heating element by interposing both ends of the heating element therebetween. This holder is composed of a pair of insulating plates made of an electric insulating material. Both ends of the heating element are formed with projections. One of the insulating plates is formed with recesses for receiving both ends of the heating element in coincidence with the shape of both ends of the heating element.
