Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a carbon black-containing electroconductive styrenic resin composition and/or an electroconductive sheet composed of the sheet which are free from surface staining due to the bleeding of a lubricant and gives a molding with controlled blocking and a static interference-protected molding obtained from the same.SOLUTION: The electroconductive resin composition includes 12-40 pts.wt. of (C) a styrenic rubber, 0.01-5 pts.wt. of (D) a non-metallic lubricant, 1-40 pts.wt. of (E1) a polyester-based resin, and/or (E2) a copolymer of ethylene and a polar vinyl monomer, its saponified product, or its ion-crosslinked product to 100 pts.wt. of the aggregate of 95-50 pts.wt. of (A) a styrenic resin, 5-50 pts.wt. of (B) carbon black (provided that A+B=100 pts.wt.). The surface resistance of the sheet obtained from the resin composition is 1×10to 1×10Ω/SQUARE. The electroconductive sheet is composed of the electroconductive resin composition. The static interference-protected molding is obtained using the electroconductive sheet.
