A dielectric ceramic composition having a main ingredient including a dielectric oxide expressed by the formula {(Me<SUB>1-x</SUB>Ca<SUB>x</SUB>)O}<SUB>m</SUB>.(Zr<SUB>1-y</SUB>Ti<SUB>y</SUB>)O<SUB>2</SUB>, where the symbol Me indicating the name of the element in said formula is at least one of Sr, Mg, and Ba and where the symbols m, x, and y indicating the molar ratios of the formulation in the formula are in relationships of 0.995<=m<1.020, 0<x<=0.15, and 0<=y<=1.00, a first sub ingredient including an oxide of R (where R is a rare earth element), a second sub ingredient including an oxide of Mg, and a third sub ingredient including an oxide of Mn, wherein the ratios of the sub ingredients with respect to 100 moles of the main ingredient are first sub ingredient: 0.1 to 6 moles (value converted to oxide of R), second sub ingredient: 0.1 to 5 moles (value converted to oxide of Mg), and third sub ingredient: 0.1 to 2.5 moles (value converted to oxide of Mn), said dielectric ceramic composition further having as a fourth sub ingredient an oxide of A (where A is at least one type of element selected from the group of anionic elements having an effective ion radius at the time of hexacoordination of 0.065 nm to 0.085 nm).
