Secondary battery and method of fabricating secondary battery

Disclosed are a secondary battery and a method of fabricating a secondary battery, which prevent an electrode plate from being damaged when an electrode tab is coupled to the electrode plate. The secondary battery includes an electrode assembly including an electrode plate and a separator. The electrode plate includes a positive electrode plate coupled with a positive electrode tab and a negative electrode plate coupled with a negative electrode tab. At least one of the positive electrode tab and the negative electrode tab is coupled to a non-coating portion of the electrode plate, to which a coating portion is not applied, has an end surround by a protective member, and a region exposed out of the protective member and coupled to the non-coating portion.
