| 内容: | The barium titanate type semiconducting ceramic of the present invention is so arranged as to contain BaTiO3 as a main component thereof, and Ba2TiSi2O8 and BanTimOn+2m (1 <= n <= 4, 2 <= m <= 13, n < m) respectively as trace-phase compositions, wherein the ratio of the contents of Ba2TiSi2O8 and BanTimOn+2m (Ba2TiSi2O8/BanTimOn+2m) as the trace-phase compositions is in the range of 0.5 to 80.0. Therefore, it is highly excellent in voltage resistance and ensures high reliability as a product element. Moreover, it has an appropriate room temperature resistivity rho 25 for fully functioning as a product element. |
