摘要：PROBLEM TO BE SOLVED: To provide a method for predicting a low electro resistant rubber sheet excellent in electroconductivity and useful for an electric cell, etc., by kneading a rubber polymer with a conductive filler and pulverizing the formed block. SOLUTION: This method for producing a low electro resistant rubber sheet comprises a step for adding (B) 100-350 pts.wt. electrocoductive filler to (A) 100 pts.wt. rubber polymer, and kneading the components A and B to provide a block containing the component B dispersed in the component A and having a viscosity higher than that of the rubber polymer, a step for pulverizing the block to provide a granular material containing the components A and B, and a step for forming the granular material. The objective sheet has preferably <=10% dispersion of thickness and 0.003-0.05Ω-cm volume specific resistance.
