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.

摘要： A sealing film forms a seal between a first metal base body and a second base body. The sealing film includes a first adhesive layer, a second adhesive layer, and a base material layer. The first adhesive layer mainly contains an acid-modified polyolefin and adheres to the first base body. The second adhesive layer mainly contains a polyolefin and adheres to the second base body. The base material layer is provided between the first adhesive layer and the second adhesive layer. The thickness of the first adhesive layer is at least 25 and at most 70 when the total thickness of the sealing film is defined as 100. The thickness of the base material layer is at least 25 and at most 70. The thickness of the second adhesive layer is at least 5 and at most 50.
