Provided is a dielectric ceramic composition comprising a main component of forsterite and calcium strontium titanate. A content ratio of forsterite in the main component is from 84.0 to 92.5 parts by mole, and a content ratio of calcium strontium titanate is from 7.5 to 16.0 parts by mole. (Sr+Ca)/Ti in the calcium strontium titanate is from 1.03 to 1.20 in terms of a molar ratio. With respect to a total of 100 parts by mass of the main component and a subcomponent except for Li-containing glass, from 2 to 10 parts by mass of Li-containing glass is added. The Li-containing glass includes AlOin an amount of from 1% by mass to 10% by mass.
