A magnetic material like Ni-Zn-Ferrite particle is added to the thermosetting resin like the epoxy. The Ni-Zn-Ferrite particle is uniformly dispersed to the thermosetting resin through the agitation process(S11). The prepared glass fiber is impregnated to the thermosetting resin mixture(S13). The resin component is solidified by heating the glass fiber impregnated to the thermosetting resin mixture at 120 degrees centigrade in an oven for one minute(S15). The prepreg is prepared through the above process. One prepared prepreg or more are stacked(S17). A vacuum process for the stacked prepreg is performed by using a vacuum pump for removing a bubble excessively generated inside(S19). The vacuum processed prepreg is hardened in the oven(S21).
