Abstract:
The method for producing a porous film of the present invention includes producing a stretched film by stretching a resin sheet containing at least polyolefin, and then irradiating the stretched film with a vacuum ultraviolet ray. The separator for a non-aqueous electrolyte battery of the present invention is composed of the porous film obtained by the production method of the present invention. The non-aqueous electrolyte battery of the present invention is provided with the separator for a non-aqueous electrolyte battery of the present invention.
