摘要: A dielectric ceramic composition includes, as a main component, a compound having perovskite type crystal structure shown by a general formula ABO3, as subcomponents, in terms of respective element with respect to 100 moles of the compound, and 0.6 to 2.0 moles of an oxide of Mg, 0.010 to 0.6 mole of oxide of Mn and/or Cr, 0.010 to 0.2 mole of an oxide of at least one selected from V, Mo and W, 0.10 to 1.0 mole of an oxide of R1 (R1 is at least one selected from Y, Yb, Er and Ho), 0.10 to 1.0 mole of an oxide of R2 (R2 is at least one selected from Dy, Gd and Tb) and 0.2 to 1.5 moles of a component consisting of an oxide of Ba and/or oxide of Ca and an oxide of Si. According to the present invention, even when a dielectric layer is made thinner, a dielectric ceramic composition having good characteristics can be provided.
