摘要：
A semiconductor ceramic device includes a semiconductor ceramic sintered body and external electrodes. The semiconductor ceramic sintered body contains a lanthanum cobalt type oxide major component, about 0.1 to 10 mol % on an element conversion basis of an oxide of Cr as a sub-component, and about 0.001 to 0.5 mol % on an element conversion basis of at least one of the oxides of Li, Na, K, Rb, Cs, Be, Mg, Ca, Sr, Ba, Ni, Cu and Zn.
