A binder for an electrode of a non-aqueous electrolyte secondary battery comprising a vinyl alcohol polymer having 30 to 95% by weight of recurring units expressed by the following formula (1): ##STR1## A slurry containing this binder, an active material and a liquid medium is used to produce an electrode. A non-aqueous electrolyte secondary battery having the electrode as a positive electrode and/or a negative electrode exhibits a minimized reduction in capacity at repeated charge-discharge cycles.
