Electronic device, dielectric ceramic composition and the production method

A dielectric ceramic composition comprising:

• a main component including barium titanate;
• a first subcomponent including MgO;
• a second subcomponent including a SiO2 based sintering aid;
• a third subcomponent including at least one selected from V2O5, MoO3 and WO3;
• a fourth subcomponent including an oxide of R1 (note that R1 is at least one selected from Y, Ho, Er, Tm, Yb and Lu);
• a fifth subcomponent including an oxide of R2 (note that R2 is at least one selected from Dy, Tb, Gd and Eu);
• and
• a sixth subcomponent including at least one of MnO and Cr2O3:
• wherein
• ratios of respective subcomponents with respect to 100 moles of said main component are
• the first subcomponent:
• 0.8 to 2 moles,
• the second subcomponent:
• 1.5 to 5 moles,
• the third subcomponent:
• 0.01 to 0.1 mole,
• the fourth subcomponent:
• 0.5 to 2 moles (note that the number of moles of the fourth subcomponent is a ratio of R1 alone),
• the fifth subcomponent:
• 1.5 to 4.5 moles (note that the number of moles of the fifth subcomponent is a ratio of R2 alone), and
• the sixth subcomponent:
• 0.1 to 0.2 mole;
• a total number of moles of the fourth subcomponent and the fifth subcomponent with respect to 100 moles of said main component is 2 to 6 moles when calculated as a conversion of said R1 and a conversion of said R2;
• and
• a ratio of the fifth subcomponent to the total number of moles of the fourth subcomponent and the fifth subcomponent with respect to 100 moles of the main component is in a relationship of 0.5≦R2/(R1+R2)≦0.75 when calculated as a conversion of said R1 and a conversion of said R2.
