Claim Text:
1. A secondary battery comprising: a bare cell for producing electricity, the bare cell including a top surface, a bottom surface facing the top surface, and a first side surface; an electrode terminal formed on the top surface, the electrode terminal having a polarity, the top surface of the bare cell having another polarity different from the polarity of the electrode terminal, the electrode terminal being electrically insulated from the top surface of the bare cell; a first case covering the top surface and the electrode terminal, the first case not covering the bottom surface, the first case not covering the first side surface; a second case completely covering the first side surface, the second case including a protective circuit module; a first lead tab coupling the electrode terminal to the protective circuit module, the first lead tab extending from an end portion of the second case to be connected to the electrode terminal, the first lead tab disposed only on the top surface of the bare cell; a second lead tab coupling the top surface of the bare cell having said another polarity to the protective circuit module, the second lead tab extending from the end portion of the second case to be connected to the top surface of the bare cell, the second lead tab disposed only on the top surface of the bare cell, both of the first and the second lead tabs being covered by the first case one of the first and second lead tabs including a bending section that shifts said one of the first and second lead tabs away from another of the first and second lead tabs; and an insulating layer formed between the first lead tab and the second lead tab for preventing short circuit between the first and the second lead tabs.
