To provide a secondary battery that is capable of shortening injecting time for injecting an electrolytic solution, and infiltrating the electrolytic solution uniformly, during a process for preparing the secondary battery. Also, to provide the secondary battery in which discordance of layers of positive-electrode plates, negative-electrode plates, and separators does not easily occur during a process for laminating them and the following process. A nonaqueous electrolytic solution secondary battery of the present invention comprises: negative-electrode plates which are rectangular; positive-electrode plates which each have a pair of opposed sides shorter than a pair of opposed sides of each negative-electrode plate; separators which each are formed of a porous resin film enclosing each positive-electrode plate; an enclosure which encloses the negative-electrode plates and separators which are laminated alternately, in which a direction of the sides of the negative-electrode plates aligns with a direction of the shorter sides of the positive-electrode plates; and an injection pathway for the nonaqueous electrolytic solution, which the pathway being formed between the negative-electrode plates between which the separator is sandwiched, the pathway being formed at edges of opposed sides of the negative-electrode plates. |
