PROBLEM TO BE SOLVED: To provide a lead member with high reliability in which an insulating film is certainly pasted up on a lead conductor, to provide a power storage device with the lead member, and to provide a manufacturing method of the lead member. SOLUTION: The lead member 21 has adhesive layers 23b of a pair of insulating films 23 mutually pasted together by thermal fusion through a lead conductor 22, and the lead conductor 22 is made of a metal material with a thickness of 0.1 mm or more and 1.5 mm or less. The adhesive layer 23b of the insulating film 23 has polypropylene of a melt-flow rate of 4g/10 minutes or more and 7g/10 minutes or less as a base resin, and its thickness is 1/5 or more and 1/2 or less of the thickness of the lead conductor 22. A crosslinking layer 23a of the insulating film 23 has a crosslinking auxiliary of 0.5 wt.% or more and 10 wt.% or less and a phenolic antioxidant of 0.1 wt.% or more and 3.0 wt.% or less added with polypropylene as a base resin, and the crosslinking auxiliary is made of a compound containing at least two pieces or more of unsaturated groups in a molecule.
