    摘要: A dielectric ceramic composition contains components, with respective numbers of moles relative to 100 moles of barium titanate, including barium titanate, a first sub-component containing at least one oxide selected from a Mg oxide, a Ca oxide, a Ba oxide, and Sr oxide, a second sub-component containing an oxide containing 1 mol of Si atoms per mol, a third sub-component containing at least one oxide selected from a V oxide, a Mo oxide, and a W oxide, a fourth sub-component containing at least one R1 oxide (wherein R1 is at least one selected from Sc, Er, Tm, Yb, and Lu), a fifth sub-component containing at least one R2 oxide (wherein R2 is at least one selected from Y, Dy, Ho, Tb, Gd, and Eu), a sixth sub-component containing at least one selected from a Mn oxide and a Cr oxide, and a seventh sub-component containing at least one selected from calcium zirconate and a mixture of a Ca oxide and Zr oxide. The ratio (A/B) of the number of moles A of the second sub-component to the total number of moles B of the fourth and fifth sub-components is 0.7 or more. Alternatively, the ratio (C/D) of the number of moles C of Si atoms in the second sub-component to the total number of moles of the atoms in the first to seventh sub-components excluding the Si atoms and oxygen atoms being 0.2 or more, and the total number of moles of the fourth and fifth sub-components being 3 or more.
