  "textContent": "The invention provides a reactive polymer-supporting porous film for use as a battery separator which comprises a porous substrate film and a partially crosslinked reactive polymer supported on the porous substrate film, the partially crosslinked reactive polymer being obtained by the reaction of a crosslinkable polymer having at least one reactive group selected from the group consisting of 3-oxetanyl group and epoxy group in the molecule with a polycarboxylic acid. The reactive polymer-supporting porous film for use as a battery separator has a separator and electrodes sufficiently bonded to each other and low inner resistance so that it is suitably used for production of battery excellent in high rate performance. Further, the invention provides a method of producing a battery which comprises placing the electrode/reactive polymer-supporting porous film layered body in a battery container; introducing an electrolytic solution containing a cationic polymerization catalyst into the battery container thereby bonding the porous film and the electrodes together.",
