PURPOSE:To obtain a dielectric porcelain composition producing method for producing a dielectric porcelain composition capable of forming a dielectric porcelain having stable dielectric properties. CONSTITUTION:The composition can be obtained by adding, by weight, <=7% ZnO, <=10% NiO, and <=7% Ta2O5 to principal components consisting of 22-43% TiO2, 38-58% ZrO2, and 9-26% SnO2. At this time, at least two kinds among TiO2, ZrO2, and SnO2 as principal components are previously calcined. |
