Method for producing resin collector for negative electrodes, method for producing negative electrode for lithium ion batteries, and method for producing lithium ion battery

A method for producing a sheet-shaped resin current collector for negative electrodes, comprising

• 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, and
• wherein the multilayered body includes a layer of a conductive resin composition containing nickel particles as the conductive filler and a layer of a conductive resin composition containing a conductive carbon as the conductive filler.
