    摘要: Provided are an electrode lead wire member including a sealing film having high adhesive strength and resistance to an electrolytic solution, and a battery including the electrode lead wire member. Provided is an electrode lead wire member including: a derivation portion extending in one direction; a surface-treated layer formed, at the derivation portion, on a surface of the derivation portion; and a sealing film provided in contact with the surface-treated layer, in which the sealing film has an adhesive resin layer in contact with the surface-treated layer, and the adhesive resin layer contains imine-modified polyolefin or modified polyolefin having a carbodiimide group.
