A glass ceramic composition includes a SrZrO3 ceramic and a Li2O-MgO-ZnO-B2O3-SiO2-based glass, wherein the Li2O-MgO-ZnO-B2O3-SiO2-based glass accounts for about 1 to about 12 weight percent of the total and includes Li2O in an amount in the range of about 3.5 to about 15 weight percent, MgO in an amount in the range of about 20 to about 50 weight percent, BaO in an amount in the range of about 0 to about 25 weight percent, CaO in an amount in the range of about 0 to about 10 weight percent, SrO in an amount in the range of about 0 to about 25 weight percent, B2O3 in an amount in the range of about 16 to about 29 weight percent, SiO2 in an amount in the range of about 11 to about 35 weight percent, ZnO in an amount in the range of about 5 to about 20 weight percent, and Al2O3 in an amount in the range of about 0 to about 15 weight percent, and the glass ceramic composition further includes a SrTiO3 ceramic in an amount in the range of about 0 to about 6 weight percent of the total. This composition is used for green glass ceramic layers defining a green laminated structure to be formed into, for example, a component body of an LC filter.
