STRUCTURALLY STABLE CURRENT COLLECTING PLATE AND CYLINDRICAL BATTERY CELL USING SAME

Provided is a current collecting plate that is connected to an electrode tab provided at one end among the two ends of the electrode assembly in the axial direction, wherein the one end is inserted into a can while facing the bottom thereof. The current collecting plate comprises: a terminal joint part that has one side surface joined to a cap, the bottom of the can, or an electrode terminal; an electrode joint part that surrounds the terminal joint part from the outside of the terminal joint part in the radial direction and has the other side connected to the electrode tab of the electrode assembly; elastic connection parts that are disposed between the electrode joint part and the terminal joint part and electrically connect the electrode joint part and the terminal joint part; and an opening that is disposed between the elastic connection parts adjacent in the circumferential direction and separates the electrode joint part and the terminal joint part in the radial direction or the axial direction.
