ELECTRODE FILM ROLLED WEB, ELECTRODE, AND ELECTRODE LAMINATE

An electrode film rolled web includes an adhesive layer, and a positive active material layer laminated on the adhesive layer, where the adhesive layer includes a particulate conductive material and a binder, the binder contains a first polyisobutylene that has a viscosity average molecular weight of 1,000,000 or more and a second polyisobutylene that has a viscosity average molecular weight of 10,000 or more and 100,000 or less, the conductive material is a carbon material, and the adhesive layer contains the conductive material in an amount of 15% by mass or more and 25% by mass or less, the first polyisobutylene in an amount of 25% by mass or more and 50% by mass or less, and the second polyisobutylene in an amount of 30% by mass or more and 60% by mass or less, based on 100% by mass in total of the conductive material and the binder.
