<P>PROBLEM TO BE SOLVED: To provide a dielectric ceramic composition which shows good characteristics, even when a dielectric layer is made thinner. <P>SOLUTION: The dielectric ceramic composition includes, as a main component, a compound having a perovskite type crystal structure expressed by the formula ABO<SB>3</SB>, and as subcomponents, in terms of respective elements with respect to 100 moles of the compound, 0.6 to 2.0 moles of an oxide of Mg, 0.010 to 0.6 mole of an 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 an oxide of Ca and an oxide of Si. <P>COPYRIGHT: (C)2011,JPO&INPIT |
