LEAD WIRE FOR NONAQUEOUS ELECTROLYTE BATTERY USE AND NONAQUEOUS ELECTROLYTE BATTERY USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide: a lead wire for nonaqueous electrolyte battery use which enables the reduction in cost, and has good resistance against electrolyte; and a nonaqueous electrolyte battery.SOLUTION: A lead wire for nonaqueous electrolyte battery use comprises: a lead conductor made of copper; a composite coating layer which covers the surface of the lead conductor; and a heat-seal layer which covers at least part of the composite coating layer. The composite coating layer which covers the surface of the lead conductor is made of a polyacrylic acid copolymer or polymethacrylic acid copolymer, or a hardened material thereof. The heat-seal layer is made of a resin composition including 0.05 pts.mass or more of a copper inhibitor to 100 pts.mass of a polyolefin-based resin.
