Since resin and ordinary molten synthetic resin are discharged concentrically and drawn and spun, no impurities or poisonous substances will enter. In addition, since the synthetic resin containing the filler is uniformly distributed on the outer circumferential side of the cross section of the fiber, good electrical conductivity can be obtained.
