NEGATIVE ELECTRODE FOR NON-AQUEOUS-ELECTROLYTE SECONDARY BATTERY, AND NON-AQUEOUS-ELECTROLYTE SECONDARY BATTERY

A negative electrode () according to an embodiment of the present invention comprises: a negative electrode core (); and a negative electrode mixture layer () that is positioned on the negative electrode core (), the negative electrode mixture layer () containing a negative electrode active material () and a water-soluble polymer (). The water-soluble polymer () is present such that an amount of 0.50 mass % or more relative to the negative electrode active material () is adsorbed onto the negative electrode active material (), and an amount of 1.05 mass % or less is separated from the negative electrode active material (). The negative electrode active material () includes a carbon material and a silicon-containing material.
