A rechargeable battery includes an electrode assembly that performs charging and discharging operations, a case having the electrode assembly enclosed therein, a cap plate coupled with an opening of the case, an electrode terminal on the cap plate, and a current collecting member connecting the electrode assembly to the electrode terminal. The current collecting member includes a terminal connecting part connected to the electrode terminal, and an electrode connecting part connected to an uncoated region of the electrode assembly, the electrode connecting part including a twisted surface, the twisted surface facing a sidewall of the case at a predetermined inclination angle with respect to a direction from the sidewall toward an end of the uncoated region.
