PROBLEM TO BE SOLVED: To provide a power storage device capable of minimizing decrease in efficiency of current collection from an electrode, and to provide a manufacturing method of an electrode assembly.SOLUTION: At an edge of an electrode assembly 11, a positive electrode tab group 15b is formed by collecting positive electrode tabs 15, for extracting a current from the electrode assembly 11, from one end to the other end in the lamination direction of the electrode assembly 11. A positive electrode conductive member 24 is connected with the positive electrode tab group 15b, and the positive electrode conductive member 24 and electrode assembly 11 are housed in a case. The positive electrode conductive member 24 is bonded to a positive electrode tab 15(H1), i.e., one end of the positive electrode tab group 15b in the overlapping direction, and a metal plate 30 is connected with a positive electrode tab 15(H2), i.e., the other end of the positive electrode tab group 15b in the overlapping direction. The positive electrode tab group 15b is sandwiched by the positive electrode conductive member 24 and metal plate 30 from the overlapping direction of the positive electrode tab group 15b. Insulation members 32, 33 are bonded to the positive electrode conductive member 24 and metal plate 30, and extending from one of the positive electrode conductive member 24 or metal plate 30 to the other. |
