PROBLEM TO BE SOLVED: To provide a conductor member, along with a tab lead using the conductor member, a junction body and a pouch type energy storage device, in which, by optimizing a shape of a copper strip, a nickel plating layer which is thinner as much as possible is formed evenly on at least a peripheral surface forming insulation property, to provide excellent sealing property and junction property when used as a tab lead.SOLUTION: A conductor member 1 is configured to include a copper strip 10 in which, being a flat plate, in width end edge parts 13a, 13b partitioned with main surfaces 11a, 11b and a width end surface 12, there is no protruding portion exceeding 2 μm in thickness direction from a main surface position across the entire length, and a nickel plating layer 20 covering at least the main surfaces 11a, 11b and the width end surface 12 of the copper strip 10.SELECTED DRAWING: Figure 2 |
