NOVELTY - The battery (100) has an electrode assembly (110) that includes a separator arranged between electrodes. A case (160) receives the electrode assembly. A cap assembly (170) seals a top end opening of case, and includes outwardly protruding terminal portions (130,150). A collector plate (120) comprises a lead portion (121) that includes an electrode connection portion (121a) and a terminal connection portion (121b). A connecting portion (121c) electrically connects electrode and terminal connection portions. A resin portion (122) covers connecting portion.    USE - Rechargeable battery for use in portable electronic apparatuses such as mobile phone, laptop computer and camcorder, and used as power source for driving motor of hybrid electric vehicle.    ADVANTAGE - The first connecting portion of first lead portion and the first terminal connection portion are covered by the first resin portion made of an insulating material such that a coupling force is increased between the first collector plate and first fastening terminal. The shape of the first collector plate is maintained by the first resin portion, even if the first collector plate is electrically disconnected by the fuse region being melted by heat generated when a high voltage due to a short-circuit is applied to the fuse region. Thus, additional short-circuits caused by an arc are prevented from occurring. Hence, improved safety is provided against arcs. The strength of collector plate is reinforced by insert-molding resin to cover some portions of the collector plate while preventing additional damages due to arc jump.
