A secondary battery is provided to prevent the failure of connection state of electrode taps with a can, electrode terminal, and electrode assembly by suppressing the movement of an electrode assembly with high frictional force with the inner surface of a can. A secondary battery comprises an electrode assembly and a can accommodating the electrode assembly. The inner surface of the can and the outmost surface of the electrode assembly are faced to each other. A non-slip part(45) for increasing the frictional force is formed on at lease one of the inner surface of the can and the outmost surface of the electrode assembly. The non-slip part is made of an uneven coating layer. |
