Abstract
An electrode includes an active material layer that includes an active material, a solid electrolyte, and a binder and a current collector that includes a substrate and a coating layer coating the substrate and being in contact with the active material layer. The binder includes a block copolymer that includes two first blocks constituted of a repeating unit having an aromatic ring and a second block located between the two first blocks. The weight average molecular weight of the block copolymer is 170,000 or more. The coating layer includes conductive carbon.
