A main object of the present invention is to provide a dielectric ceramic composition excellent in chemical durability that can be sintered at a low temperature without increasing the amount of subcomponents added. The main component includes a component represented by the compositional formula {α (xBaO · yNd 2 O 3 · zTiO 2 ) + β (2MgO · SiO 2 )}, and contains BaO, Nd 2 O 3 , and TiO 2 . X, y, and z representing the molar ratio are in specific ranges, respectively, and α and β representing the volume ratio of each component (xBaO.yNd 2 O 3 .zTiO 2 and 2MgO.SiO 2 ) in the main component are Each of them is in a specific range, and includes zinc oxide, boron oxide and glass having a softening point below a specific temperature as subcomponents with respect to the main component, and these subcomponents are respectively aZnO and bB 2 O. 3 , and c glass, a, b, and c each representing a mass ratio of each subcomponent to the main component are in specific ranges.
