Abstract
The invention provides a rapid temperature rise heater element comprising an exothermic section (1) and a lead section (2), the exothermic section (1) comprising an exothermic section conductor of ceramic material which includes at least four stacked exothermic section conductive layers (1a) with an exothermic section insulating layer (1c) of ceramic material interposed therebetween and connections (1b) each for connecting adjacent exothermic section conductive layers (1a). The lead section (2) includes first and second lead section conductive layers (2a and 2b) electrically connected to the uppermost and lowermost exothermic section conductive layers (1a), respectively, the first and second lead section conductive layers (2a and 2b) being stacked with a lead section insulating layer (2c) of ceramic material interposed therebetween. A durable rapid temperature rise heater element can be efficiently fabricated at low cost while maintaining heater performance.
