Research Abstract	In this study, the electrically conductivity injection molded article that used the cupper-plated fiber was focused. As a measurement result of volume resistivity in the electrically conductive injection molded article, the material which was high shear stress during injection molding showed high volume resistivity because of the plated fiber turns to the molding direction by the resin flow. In addition, we clarified that the volume resistivity and effect of electro-magnetic interference sealed were related to the flow induced shear stress. These results indicate that the electrical conductivity of injection molded article can be controlled from shear stress during injection molding.
