Dielectric ceramic composition and dielectric ceramics

The present invention provides a dielectric ceramic composition comprising: 30 to 90% by weight of a crystallized glass powder capable of depositing a diopside crystal, 1 to 40% by weight of a calcium titanate powder, a strontium titanate powder or a mixed powder thereof, and 0 to 60% by weight of at least one kind of a powder selected from the group consisting of Al₂O₃, TiO₂, ZrO₂, MgTiO₃, BaTi₄O₉, La₂Ti₂O₇, Nd₂Ti₂O₇, Ca₂Nb₂O₇, SrZrO₃ and CaZrO₃, and a dielectric ceramics obtained by firing the same.
