ABSTRACT:
A resistance ceramic heater including a ceramic substrate, and a heating element which has a resistance heat-generating portion, and electrical leads connected to the heat-generating portion for energizing the heat-generating portion to generate heat. The heat-generating portion consists of a plurality of electrically resisitive heat-generating conductors formed in parallel connection with each other and in series connection to the electrical leads, and a plurality of connecting conductors which connects the heat-generating conductors, at a plurality of connection points on each of the heat-generating conductors. The connecting points are spaced apart from each other along the length of each heat-generating conductor. An electrochemical element and an oxygen analyzer or sensor which uses the ceramic heater are also disclosed.
