Abstract

A glass-ceramic-ferrite composition containing a glass, a ferrite, and a ceramic filler, in which the glass contains, by weight, about 0.5% to about 5.0% RO (R represents at least one selected from the group consisting of Li, Na, and K), about 5.0% or less AlO, about 10.0% to about 25.0% BO, and about 70.0% to 85.0% SiOwith respect to the total weight of the glass, the percentage by weight of the ferrite is about 10% to 80% with respect to the total weight of the composition, the ceramic filler contains at least forsterite selected from forsterite and quartz, the percentage by weight of the forsterite is about 1% to about 10% with respect to the total weight of the composition, and the percentage by weight of the quartz is about 40% or less with respect to the total weight of the composition.
