摘要： The present invention aims to provide a method for producing a pinhole-free thin resin current collector for negative electrodes. The method for producing a sheet-shaped resin current collector for negative electrodes of the present invention includes stacking three or more layers of melts of conductive resin compositions each containing a polyolefin and a conductive filler to obtain a multilayered body, wherein the polyolefin contained in each of the conductive resin compositions that form the respective layers of the multilayered body has a melt mass flow rate of 15 to 70 g/10 min as measured at a temperature of 230° C. and a load of 2.16 kg in accordance with JIS K7210-1:2014.
