Patent ID: 8053385

Claim:
A dielectric ceramic composition comprising a main component including a compound satisfying a compositional formula of (Sr x Ba 1-x ) m TiO 3 wherein “x” in said compositional formula is 0.159≦“x”≦0.238, and “m” is 0.997≦“m”≦1.011, and a subcomponent comprising CaTiO 3 , at least one oxide of element selected from a group consisting of Fe, Co, Ni, Cu and Zn, an oxide of element “A” where “A” is at least one element selected from a group consisting of Mn and Cr, and an oxide of element “D” where “D” is at least one element selected from a group consisting of La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, and Y; wherein with respect to 100 weight % of said main component, CaTiO 3 is 11 to 25 weight %, and at least one oxide of element selected from the group consisting of Fe, Co, Ni, Cu, and Zn in terms of FeO 3/2 , CoO 4/3 , NiO, CuO, and ZnO is 0.10 to 0.50 weight %; and with respect to 100 mol % of said main component, the oxide of element “A” in terms of Mn element and Cr element is 0.590 to 1.940 mol %, and a ratio (A/D) of the element “A” with respect to element “D” in terms of molar ratio is 2.250 to 7.450.
