Abstract
A dielectric ceramic composition includes a component represented by composition formula {α(xBaO.yNdO.zTiO)+β(2MgO.SO)} as a main component and zinc oxide, boron oxide, and a glass having a softening point equal to or lower than a certain temperature as minor components with respect to the main component. In the dielectric ceramic composition, x, y, and z that respectively represent molar ratios of BaO, NdO, and TiOare in certain ranges and α and β that represent volume ratios of subcomponents (xBaO.yNdO.zTiOand 2MgO.SiO) in the main component are in certain ranges. When the minor components are respectively represented by aZnO, bBO, and cglass, a, b, and c that represent mass ratios of the respective minor components to the main component are in certain ranges.
