Disclosed herein are a ferrite composition for a high frequency bead in that a part of Fe in M-type hexagonal ferrite represented by BaFeOis substituted with at least one metal selected from a group consisting of 2-valence, 3-valence and 4-valence metals, as well as a chip bead material using the same. According to embodiments of the present invention, the dielectric composition is characterized in that a part of Fe as a constituent of M-type hexagonal barium ferrite is substituted by other metals, to thus decrease a sintering temperature to 920&#xb0; C. or less without using any additive for low temperature sintering. Moreover, because of high SRF properties, the inventive composition is applicable to a multilayer type chip bead used at a high frequency of more than several hundreds MHz and a magnetic antenna.

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 (FeO) 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 (BO). The ceramic electronic component manufactured by using the magnetic material composition for the ceramic electronic component has an excellent Q.
