Abstract: Disclosed is a semiconductor ceramic composition wherein a part of Ba in BaTiO3 containing no Pb is substituted by Bi-Na. The semiconductor ceramic composition is characterized in that the Curie temperature is shifted to the positive direction without using Pb and the resistivity at room temperature is greatly reduced. Also disclosed is a method for producing such a semiconductor ceramic composition. Specifically disclosed is a semiconductor ceramic composition having a composition formula expressed as [(BiNa)xBa1-x]TiO3 wherein x satisfies the following formula: 0
