A binder resin (30), which is a compound having a chemical structure that contains a polyvinylidene fluoride molecular chain (20), a six-membered ring such as a cyclohexane ring (21), and an end group (22) selected from the group consisting of SiX 3 , S, N, GeX 3 , and TiX 3 (wherein X is a functional group that undergoes a condensation reaction), wherein the six-membered ring is disposed in a region between the polyvinylidene fluoride molecular chain (20) and the end group (22), is mixed with an active material and applied to a metal foil, and the binder resin (30) is chemically bonded to metal atoms such as copper atoms (36) on the surface of the metal foil.",
