It is intended to provide a semiconductor ceramic composition capable of shifting the Curie temperature to a positive direction as well as of obtaining an excellent jump characteristic while suppressing an increase in room temperature resistivity to a minimum value. There is provided a semiconductor ceramic composition in which a portion of Ba of BaTiO3 is substituted by Bi—Na, the semiconductor ceramic composition being obtained by sintering a mixed calcined powder of a BT calcined powder containing (BaR)TiO3 or Ba(TiM)O3 (wherein each of R and M is a semiconductive dopant), wherein a part of BaCO3 and TiO2 are remained therein; and a BNT calcined powder containing a (BiNa)TiO3 powder.
