Abstract: A dielectric ceramic composition includes, as a main component, a perovskite compound containing Sr and Zr and may contain Ca and/or Ti, further contains Li and Si, and may contain Mn. When a total content of Zr and Ti is 100 parts by mol, a total content (100×m) of parts by mol of Sr and Ca is 0.8≤m≤1.3, a content a of parts by mol of Mn is 0≤a≤10, a content b of parts by mol of Li is 5≤b≤15, a content c of parts by mol of Si is 20≤c≤40, a molar ratio x of Ca/(Sr+Ca) is 0≤x≤0.8, and a molar ratio y of Ti/(Zr+Ti) is 0≤y≤0.5.
