Abstract
A ceramic heater including a plate member made of insulating ceramics in which one or more pair(s) of through-holes are formed, a rod member made of conductive ceramics with a power-supply terminal at one end. The rod member is inserted into the through hole in the plate member. A conductive layer made of conductive ceramics is formed on the plate member; and a coating layer made of insulating ceramics is formed on the conductive layer. One end face of the rod member has a same plane with a main surface of the plate member, the conductive layer has a heater pattern formed on the main surface of the plate member, and the rod members are electrically insulated not to be short-circuited to each other in the opposite main surface.
