Abstract: A nonaqueous electrolyte secondary battery includes: an electrode body; a nonaqueous electrolyte liquid; a metal-made exterior package receiving the electrode body and the nonaqueous electrolyte liquid; and a pressing member provided between the electrode body and the exterior package. An outer circumference surface of the electrode body includes an exposing section to which a surface of a negative electrode collector forming the negative electrode is exposed. In addition, the pressing member expands when absorbing the nonaqueous electrolyte liquid and presses the exposing section of the electrode body to an inner surface of the exterior package.
