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 0.5μm, a specific resistance of 103Ω.cm or more and initial permeability μiac of 8W2,000 can be used as the magnetic powder. It is desirable that amount of magnetic powder contained is 60W95wt% for the diarylphtalate resin raw material.
