摘要:
A dielectric ceramic composition comprises barium titanate as a main component, and as subcomponents, 1.00 to 2.50 moles of an oxide of Mg, 0.01 to 0.20 mole of an oxide of Mn and/or Cr, 0.03 to 0.15 mole of an oxide of at least one element selected from a group consisting of V, Mo and W, 0.20 to 1.50 mole of an oxide of R1 where R1 is at least one selected from a group consisting of Y and Ho, 0.20 to 1.50 mole of an oxide of R2 where R2 is at least one selected from a group consisting of Eu, Gd and Tb and 0.30 to 1.50 mole of an oxide of Si and/or B, in terms of each oxide with respect to 100 moles of the barium titanate.
