Abstract
A non-aqueous electrolyte battery has a positive electrode, a negative electrode, an insulating layer present between the positive electrode and the negative electrode, and an electrolytic solution holding layer that composes the insulating layer and includes an electrolytic solution and a porous polymer compound, in which the electrolytic solution is held in the pores in the porous polymer compound and swells the porous polymer compound, the material of the porous polymer compound includes a vinylidene fluoride polymer, the vinylidene fluoride polymer is a vinylidene fluoride homopolymer or a copolymer including a vinylidene fluoride monomer unit and a hexafluoropropylene monomer unit, the mass composition ratio of the monomer units of the vinylidene fluoride polymer, or vinylidene fluoride monomer units:hexafluoropropylene monomer units, is 100:0 to 95:5, and the weight average molecular weight of the vinylidene fluoride polymer is 500,000 or more to less than 1.5 million.
