ABSTRACT:
A method of producing a laminated PTC thermistor involves alternately laminating electroconductive pastes to form internal electrodes and ceramic green sheets to form semiconductor ceramic layers with a positive resistance-temperature characteristic to form a laminate, firing the laminate to form a ceramic piece, and forming external electrodes on both of the end-faces of the ceramic piece, and heat-treating the ceramic piece having the external electrodes formed thereon at a temperature between about 60° C. and 200° C.
