PURPOSE:To have a non-aqueous electrolytic liquid battery with enhanced anti- leakage performance by providing a silicon rubber layer in the joint surfaces between the sealing lid and insulative packing and by fitting it fast to the opening of the armoring can. CONSTITUTION:Polypropylene resin etc. is injected at the edge of a sealing lid 9 to make an insulative packing 8 into a solid single body. A one-liquid silicon rubber solution is dripped at the joint part between this sealing lid 9 and insulative packing 8 to be hardened there for formation of a silicon rubber layer 12. The lid 9 is then fitted to the opening of the armoring can 1, which accommodates a positive pole 6, a light-metal negative pole 5 and a non-aqueous electrolytic liquid and fastened by a folded edge 1' of the can 1 with the aid of the insulative packing 8. At this time of fitting the lid 9, the silicon rubber layer 12 bites into the sealing lid 9 and insulative packing 8, that will give with its high tightness a non-aqueous electrolytic battery having excellent anti-leakage performance. |
