Abstract
A ceramic heater device has a housing section and a heating section. The heating section includes a sintered ceramic insulator attached to a metal housing and a U-shaped sintered ceramic heater body fixed to the insulator, so that the heater body is supported by the housing section by means of the insulator in order to avoid a direct connection between the metal housing and the heater body. As a result, heat generated at the heater body may not be transferred to the metal housing, and thereby the heat can be effectively used to ignite a mixture of air and fuel in an engine and a rigid and stable support of the heater body to the metal housing can be obtained.
