Abstract
A three-dimensional ceramic heater, such as a cylindrical ceramic heater, is proposed in which the conductive ceramic heating element is multi-furcated into lanes at least in the folded-back sections so that the electric current tends to flow in a more uniform and hence laminar manner with the effect that the localized over heating is suppressed greatly.
