A method for the adhesion of vinylidene fluoride resins to metal substrates which is charaterized in that, when sticking polyvinylidene fluoride resin to a metal substrate, (a) vinylidene fluoride resin, (b) at least one type of polymer selected from acrylic and methacrylic polymers with functional groups which exhibit bonding properties or affinity in terms of metals, and (c) an organic compound with at least one functional group selected from the mercapto group, thioether group, carboxylic acid group and carboxylic acid anhydride group, are added to and mixed with vinylidene fluoride resin; an electrode constructed using said method for a battery electrode where an electrode constitutional material layer comprising electrode active material and binder is formed on at least one surface of a current collector; and a non-aqueous battery employing said electrode.
