A secondary battery is provided. In one aspects of the invention, the secondary battery includes an electrode assembly having a first electrode tab and a second electrode tab drawn out therefrom; and a case accommodating the electrode assembly, wherein a movement prevention tape, which exhibits adhesiveness when it contacts an electrolyte, is attached to at least one portion of at least one of the first electrode tab and the second electrode tab. The secondary battery includes a movement prevention tape attached to an electrode tab drawn out to the outside of an electrode assembly exhibiting adhesiveness when it contacts an electrolyte, and the electrode tab is securely fixed to the case by an adhesive force of the adhesive portion of the movement prevention tape. Accordingly, the secondary battery can prevent the electrode tab from moving inside the case due to an external impact, such as an external vibration or a drop. |
