Abstract:
1. A dielectric ceramic composition comprising a substance represented by general formula 100(Ba 1−x Ca x ) m TiO 3 +aMnO+bCuO+cRO n , wherein the coefficients 100, a, b and c each represent a mols; R represents at least one element selected from the group consisting of Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu; and n represents a number determined by the valence of the rare-earth element R and is a positive number required for maintaining electroneutrality and d parts by weight per 100 parts by weight of the compound represented by (Ba 1−x Ca x ) m TiO 3 of a sintering aid, wherein
