Abstract: Disclosed herein are a ferrite composition for a high frequency bead in that a part of Fe in M-type hexagonal ferrite represented by BaFe12O19 is 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° 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.
