A rechargeable battery including a cathode and an anode each capable of inserting and extracting an electrode reaction material, and including an electrolyte, in which the anode includes an anode current collector which is formed by including a current collector body. The anode current collector is provided thereon with an active anode material layer, and a plurality of conductive particles disposed on the surface of the current collector body with the surface facing the active anode material layer. The plurality of conductive particles is formed to include spherical particles and plate-like particles. Since a tridimensional structure having irregularities is formed on the surface of the current collector body with the spherical particles and plate-like particles, anchoring effects are greatly increased. As a result, the adhesion of the active anode material layer to the anode current collector is considerably improved. |
