PROBLEM TO BE SOLVED: To obtain a resin molding material improved in dispersion of a conductive filler, electromagnetic shielding properties and molded appearance by compounding a styrene-acrylonitrile copolymer contg. a conductive filler with another thermoplastic resin. SOLUTION: 1-69 wt.%, pref. 5-40 wt.%, still pref. 10-35 wt.%, conductive filler having a diameter of 1-500μm, pref. 3-100μm, still pref. 5-60μm, and a resistance of 10<10>Ω/square or lower, pref. 10<6>Ω/square or lower, still pref. 10<2>Ω/square or lower, further pref. 10<-1>Ω/square or lower, 1-69 wt.%, pref. 2-40 wt.%, still pref. 3-30 wt.%, styrene-acrylonitrile copolymer and 30-98 wt.% thermoplastic resin other than a styrene-acrylonitrile copolymer are compounded, thus giving a conductive resin compsn. with a high electromagnetic shielding effect and excellent mechanical properties at a low loading of the conductive filler.
