Abstract:
1. A dielectric ceramic composition having at least a main component including barium titanate, a first subcomponent including at least one type of compound selected from MgO, CaO, BaO and SrO, a second subcomponent including at least one type of compound selected from Al a third subcomponent including at least one type of compound selected from V a fourth subcomponent including an oxide of R1 (where R1 is at least one type of element selected from Sc, Er, Tm, Yb and Lu), and a fifth subcomponent including CaZrO the ratios of the subcomponents with respect to said main component as 100 mol are: first subcomponent: 0.1 to 3 mol, second subcomponent: 1 to 10 mol (however, number of moles of second subcomponent is ratio converted to Al, Li or B elements), third subcomponent; 0.01 to 0.5 mol, fourth subcomponent: 0.5 to 7 mol (however, number of moles of fourth subcomponent is ratio converted to R1 alone), fifth subcomponent: 0<fifth subcomponent≦5 mol.
