To provide a manufacturing method of an electrode/separator junction having high productivity without causing mutual shear movement between an electrode and a separator in manufacturing a battery.
This manufacturing method of an electrode/separator junction is characterized by that a partially cross-linking adhesive prepared by reacting and partially cross-linking multifunctional isocyanate with a reactive polymer having a functional group capable of reacting with an isocyanate group is supported to a porous film to obtain a partially cross-linking adhesive supporting porous film; an electrode/porous film layered product is obtained by sticking an electrode to the partially cross-linking adhesive supporting porous film; and next the electrode/porous film layered product is immersed into an electrolyte containing multifunctional isocyanate and heated to react the reactive polymer in the partially cross-linking adhesive included in the electrode/porous film layered product with the multifunctional isocyanate so that the electrode is stuck to the porous film by cross-linking and solidifying the reactive polymer.
