PURPOSE:To obtain a magnetic material having excellent workability, heat resistivity and fluidity during thermal molding by containing magnetic material powder to the diarylphtalate resin raw material. CONSTITUTION:Diarylphtalate resin raw material can be obtained from oligomer of diarylphthalate or by dissolving it into the diarylphtalate monomer. Meanwhile, a magnetic powder is adequately determined in accordance with application field of magnetic material. For example, in case a magnetic material is used for shield, ferrite powder having a grain size of 0.5mum, a specific resistance of 10<3>OMEGA.cm or more and initial permeability muiac of 8-2,000 can be used as the magnetic powder. It is desirable that amount of magnetic powder contained is 60-95wt% for the diarylphtalate resin raw material. |
