Abstract
Battery elementis sandwiched between and surrounded by casing filmseach having a thermo-fusing resin layer, and is sealed by thermally fused regionformed by thermally fusing around the overall periphery. Cross-link structure portionis formed in part of thermally fused regionby cross-linking casing film, and gas release chamberis formed with its leading end positioned in cross-link structure portion. Gas release chamberis a portion which is surrounded by thermally fused regionalong its periphery, and in which casing filmsare not thermally fused. Tubewhich is open at both ends is connected to gas release chamber, while sandwiched between casing films, with its leading end positioned in gas release chamber
