PURPOSE: An adhesive tape for non-aqueous battery is provided to improve injection properties into a battery case without causing degradation of battery powder, and to prevent short circuit between electrodes due to burr existing on an electrode plate. CONSTITUTION: An adhesive tape(3) for non-aqueous battery comprises a substrate(1), and an adhesive layer(2) on at least one side of the substrate. The adhesive layer comprises 90 weight% or more of polyisobutylene rubber. The content of polyisobutylene rubber of which molecular weight is 800,000-2,200,000, is 15-50 weight%, the content of polyisobutylene rubber of which molecular weight is 10,000-700,000 is 35-70 weight%, the content of components of which molecular weight is 10,000 or less is 5 weight%, on the basis of whole adhesive layer. |
