  "textContent": "An object of the invention is to provide a process for producing non-aqueous battery electrode-forming binder solutions which includes a step of performing filtration with a filtration accuracy that enables suppressing of the occurrence of internal short circuits (shorts) in non-aqueous batteries such as lithium ion secondary batteries. A process for producing non-aqueous battery electrode-forming binder solutions of the invention includes a step (A) of filtering a polymer solution of a vinylidene fluoride resin in an organic solvent through a filter membrane (a) that is made of a polyolefin resin and has an initial filtration efficiency of not less than 99.9% for a filtering particle size of 20 µm.",
