Dielectric ceramic composition

A dielectric ceramic composition comprising:

• as a main component, a component represented by a composition formula {α(xBaO.yNd2O3.zTiO2)+β(2MgO.SiO2)}, wherein x, y, and z representing a molar ratio of BaO, Nd2O3, and TiO2 are in the ranges:
• 14 (mol %)≦x≦19 (mol %),
• 12 (mol %)≦y≦17 (mol %), and
• 65 (mol %)≦z≦71 (mol %), respectively,
• and satisfy the relationship x+y+z=100, and α and β representing a volume ratio of each component in the main component are in the ranges:
• 35 (vol %)≦α≦65 (vol %) and
• 35 (vol %)≦β≦65 (vol %), respectively,
• and satisfy the relationship α+β=100 (vol %);
• and
• as minor components with respect to the main component, zinc oxide, boron oxide, a glass having a softening point of 570° C. or less, and silver, wherein when these minor components are represented as aZnO, bB2O3, cglass, and dAg, respectively, a, b, c and d representing a mass ratio of each of the minor components based on the main component are in the ranges:
• 0.5 (mass %)≦a≦12.0 (mass %),
• 0.5 (mass %)≦b≦6.0 (mass %),
• 0.1 (mass %)≦c≦10.0 (mass %), and
• 0.1 (mass %)≦d≦3.0 (mass %), respectively.
