ABSTRACT:
A semiconductor ceramic composition of a barium titanate system comprises a main component containing a minor quantity of one or more semiconductor-forming elements, and additives of manganese oxides and silica incorporated therein, and is characterized by that the main component consists essentially of 30 to 95 mol % of BaTiO.sub.3, 3 to 25 mol % of CaTiO.sub.3, 1 to 30 mol % of SrTiO.sub.3 and 1 to 50 mol % of PbTiO.sub.3. The contents of manganese oxides and silica are 0.03 to 0.15 mol %, preferably, 0.03 to 0.10 mol % in terms of Mn, and 0.5 to 5 mol % in terms of SiO.sub.2, respectively, with respect to one mole of the main component. One or more semiconductor-forming elements are selected from the group consisting of rare earth elements, Nb, Bi, Sb, W and Th, and the content of the elements is 0.2 to 1.0 mol %.
