Embodiments provide a secondary battery, which can suppress deformation of an electrode assembly and a current collector by installing a damping member between a non-coating portion of the electrode assembly and a can. In one embodiment, the secondary battery includes a can having an accommodating space and an open top portion; a plurality of electrode assemblies inserted into the can; a current collector connected to the non-coating portion of the electrode assembly; a damping member made of an elastic material between the electrode assembly and the can; and a cap plate sealing the can.
