    • A storage battery which can further intensify the sealing properties of the electrode rod piercing portion thereof, a technique capable of increasing the area of the sealing surface at the sealed portion of the storage battery, a technique capable of certainly preventing the missing of mounting of a rubber-based sealing material corresponding to O-ring at the sealed portion of the storage battery, and an insulating material having an excellent corrosion resistance to highly corrosive battery content and a battery container including same are provided.An electrode rod 14 is allowed to extend upward through an annular member 15, a pressing member 18 is placed on the annular member 15, and a nut 22 is then threaded on a thread portion 21. This threading job is effected until the pressing member 18 is placed on and stopped by a collar portion 23. At the time when threading ends, a neck portion 25 is somewhat compressed to exhibit sealing properties. At the same time, a head portion 26 is drastically compressed and thus forms a first sealing portion at Point P1, a second sealing portion at Point P2 and a third sealing portion at Point P3. Further, while a disc sealing member 23 being properly compressed by the annular member 15 made of a resin and a current collecting plate 17, they are put in a vacuum heating furnace where they are then subjected to heat treatment at 160° C. in vacuo for 72 hours. This heat treatment allows PET film 25 to be heat-fused to the annular member 15 made of a resin and PET film 26 to be heat-fused to the current collecting plate 17. Moreover, a lid body 12 is formed integrally with an annular member 15 of rubber having a spindle-shaped section. And, this annular member 15 of rubber is bonded to PET film 32, 32 by the action of adhesive layer 33, 33. Since this bonding is firm, the annular member 15 of rubber cannot be detached from the lid body 12 during use.Further, an insulating material for electrode mounting to be used in a battery container which is made of a polyethylene terephthalate resin and a container having a lid member obtained by forming a polyester resin-coated aluminum sheet double-seamed attached to the opening of the body of a can are provided, and a polyethylene terephthalate resin insulating material for electrode mounting is attached to a through-hole provided piercing the central part of the lid member with an adhesive including (B) a hardener made of at least one of phenolic resin, amino resin and polyisocyanate resin incorporated in (A) a polyester resin including a dicarboxylic acid component mainly including terephthalic acid and a glycol component and having a glass transition temperature of from 30° C. to 110° C., whereby the battery content has an excellent corrosion resistance to the electrolyte including a highly corrosive propylene carbonate salt as a main component, etc. and an enhanced leakage resistance.
