Abstract
In a ceramic heater applicable to an oxygen concentration sensor used to detect an oxygen concentration sensor in an exhaust gas of an internal combustion engine, a heating pattern constituted by an electrically resistive body comprises a plurality of radially extended segments on an outer peripheral surface of a cylindrical main body made of a ceramic material. Since a length of an axially extended segment of the heating pattern on the cylindrical main body is excessively short, a tip of a squeege can be prevented from pressing a mask used to make, for example, a curved surface printing using an electrically resistive conductive paste.
