Abstract
There are provided a composition for a ceramic electronic component having excellent sinterability and magnetic characteristics (Q), a manufacturing method thereof, and an electronic component using the same. The magnetic material composition for the ceramic electronic component is composed of ferric oxide (Fe2O3) of 47.0 to 49.0 parts by mole, nickel oxide (NiO) of 16.0 to 24.0 parts by mole, zinc oxide (ZnO) of 18.0 to 25.0 parts by mole, and copper oxide (CuO) of 7.0 to 13.0 parts by mole, wherein a portion of ferric oxide may be substituted with boron oxide (B2O3). The ceramic electronic component manufactured by using the magnetic material composition for the ceramic electronic component has an excellent Q.
