Patent ID: 6946418

Claim:
A dielectric ceramic comprising: a primary constituent represented by general formula (1): a [(Sr b Ca 1-b )TiO 3 ]−(1 −a )[Bi 2 O 3 .n TiO 2 ] (wherein a and b indicate molar amounts, and n indicates a molar ratio of TiO 2 to Bi 2 O 3 ); and a secondary constituent represented by general formula (2): x MgTiO 3 −y MnO m −z Ln 2 O 3 (wherein x, y, and z indicate weight amounts per 100 parts by weight of the primary constituent, m is 1 to 2, and Ln is at least one element selected from the group consisting of La, Ce, Pr, Nd, Sm, Eu, Gd, Dy, Ho and Er), and wherein a, b, n, x, y, and z satisfy the expressions 0.88≦a≦0.92, 0.3≦b≦0.5, 1.8≦n≦3, 1≦x≦3, 0.1≦y≦2, and 0<z≦3.
