PROBLEM TO BE SOLVED: To provide a power storage device in which a fusion member is deployed that can secure air tightness inside an outside packaging member even if distance between a positive electrode outer lead terminal and a negative electrode outer lead terminal is narrowed.SOLUTION: A laminating type battery is equipped with a flexible outer packaging member having a sealing part in which an electrode lamination stack of positive electrode and negative electrode is sealed, the positive electrode outer lead terminal 21 and the negative electrode outer lead terminal 31 which are connected to respective terminals of the positive electrode and the negative electrode and led out in the same direction from the sealing part of the outer packaging member, and a positive electrode side fusion member 22 and a negative electrode side fusion member 32 that are arranged to be respectively interposed between the sealing part of the outer packaging member, and the positive electrode outer lead terminal 21 and the negative electrode outer lead terminal 31. The positive electrode side fusion member 22 and the negative electrode side fusion member 32 are formed to be mutually jointed. |
