A dielectric ceramic contains a primary constituent represented by general formula (1): a[(Sr<SUB>b</SUB>Ca<SUB>1-b</SUB>)TiO<SUB>3</SUB>]-(1-a)[Bi<SUB>2</SUB>O<SUB>3</SUB>.nTiO<SUB>2</SUB>] (wherein a and b indicate molar amounts, and n indicates a molar ratio of TiO<SUB>2 </SUB>to Bi<SUB>2</SUB>O<SUB>3</SUB>), and a secondary constituent represented by general formula (2): xMgTiO<SUB>3</SUB>+yMnO<SUB>m</SUB>+zLn<SUB>2</SUB>O<SUB>3 </SUB>(wherein x, y, and z indicate weight per 100 parts by weight of the primary constituent, m is 1 to 2, and Ln is at least one of La, Ce, Pr, Nd, Sm, Eu, Gd, Dy, Ho, and Er), wherein a, b, n, x, y, and z satisfy the expressions 0.88<=a<=0.92, 0.30<=b<=0.50, 1.8<=n<=3.0, 1.0<=x<=3.0, 0.1<=y<=2.0, and 0<z<=3.0. A ceramic electronic component including the dielectric ceramic is also disclosed.
