PURPOSE: To provide a high-reliability positive temperature coefficient thermistor usable for heating elements or switching elements the characteristics of which little deteriorates even when used in a reducing atmosphere. CONSTITUTION: To a main component composed of Ba titanate or its solid soln. a semiconductor element, oxides of Mn, Al and Si, and Ba(1+ X) TiO3 powder (X ranges between 0.05 and 0.03) 0.5-30mol% are added to form a compact and it is baked and electrodes are formed thereafter. |
