an electrode assembly;
a case containing the electrode assembly;
a cap plate covering an opening of the case; and
a current collecting member comprising:
a current collecting portion coupled to the electrode assembly;
a terminal coupling portion extending substantially perpendicularly from the current collecting portion to form a corner portion

member, the terminal coupling portion extending away from the corner portion in a lengthwise direction of the terminal coupling
portion; and

a fuse portion configured to pass a current therethrough and having a cross-sectional area that is smaller than that of other
portions of the current collecting member,
