In a rechargeable battery, a case is combined with an upper surface of a bare cell by being fixed to a lead plate electrically coupling a protection circuit board of a protection circuit module to the bare cell. Alternatively, the case is combined with the bare cell by being fixed to the protection circuit board so as not to be separated from the bare cell, thereby improving the reliability of the products.
