ABSTRACT:
A semiconductive ceramic composition capable of exhibiting excellent electrical and physical characteristics sufficient to be used for a boundary-layer type semiconductive ceramic capacitor and such a capacitor capable of being increased in dielectric constant and insulation resistance and exhibiting excellent solderability and tensile strength of electrodes. The composition includes a SrTiO.sub.3 base material and an additive for semiconductivity consisting of Y.sub.2 O.sub.3 and Nb.sub.2 O.sub.5. The Y.sub.2 O.sub.3 and Nb.sub.2 O.sub.5 each are present in an amount of 0.1 to 0.4 mol % based on the composition. The capacitor includes a semiconductive ceramic body formed of the composition, a first conductive layer formed on each of both surfaces of the body and a second conductive layer formed on the first conductive layer. A process for manufacturing the capacitor is also provided.
