description A secondary battery includes an electrode assembly; a first pouch including an internal space accommodating the electrode assembly; and a second pouch coupled to at least one part of the first pouch and thermally bonded to at least one part of the first pouch, the first pouch and the second pouch sealing the electrode assembly. The first pouch and the second pouch each includes a body portion contacting the electrode assembly, the body portion comprising a back side, a front side opposite the back side, and two side surfaces between the back side and the front side; and a pair of wing portions respectively protruding from the two side surfaces of the body portion. A width of each of the pair of wing portions varies along the longitudinal direction of the electrode assembly such that the width of a central part of each of the pair of wing portions is greater than the width of either end part of each of the pair of wing portions.
