Zusammenfassung:Provided is a dielectric ceramic composition including a first component and a second component, wherein the first component comprises an oxide of Ca of 0.00 mol% to 35.85 mol% an oxide of Sr of 0.00 mol% to 47.12 mol%, an oxide of Ba of 0.00 mol% to 51.22 mol%, an oxide of Ti of 0.00 mol% to 17.36 mol%, an oxide of Zr of 0.00 mol% to 17.36 mol%, an oxide of Sn of 0.00 mol% to 2.60 mol%, an oxide of Nb of 0.00 mol% to 35.32 mol%, an oxide of Ta of 0.00 mol% to 35.32 mol%, and an oxide of V of 0.00 mol% to 2.65 mol%, and the second component includes at least (a) an oxide of Mn of 0.005% by mass to 3.500% by mass and (b) an oxide of Cu and/or an oxide of Ru. According to the present invention, a dielectric ceramic composition having a high insulation resistance value, a small change in electrostatic capacity even under a high temperature environment, and small dielectric losses at 25°C and at 200°C can be provided.
