PURPOSE:To provide an excellent high permittivity dielectric porcelain composition with a small permittivity loss, whose permittivity hardly varies across a wide temperature range. CONSTITUTION:0.2-7.0weight% of SrZrO3 is contained, as an additive, in a main composition which consists of 94.0-99.0mol% of BaTiO3, 0.5-3.0mol% of Nb2O5 and 0.5-3.0mol% of ZnO. |
