<P>PROBLEM TO BE SOLVED: To provide a dielectric ceramic composition having excellent high temperature load lifetime and a capacitance-temperature characteristic as well as suppressed electrostriction. <P>SOLUTION: The dielectric ceramic composition includes a main component including barium titanate, a first subcomponent including MgO, a second subcomponent including sintering aids of SiO<SB>2</SB>compound, a third subcomponent including at least one of V<SB>2</SB>O<SB>5</SB>, Nb<SB>2</SB>O<SB>5</SB>and WO<SB>3</SB>, a fourth A subcomponent including R<SP>A</SP>oxide (note that, R<SP>A</SP>is at least one selected from Tb, Gd and Dy), a fourth B subcomponent including R<SP>B</SP>oside (note that, R<SP>B</SP>is at least one selected from Ho, Y and Yb), and a fifth subcomponent including MnO or Cr<SB>2</SB>O<SB>3</SB>. <P>COPYRIGHT: (C)2010,JPO&INPIT |
