This negative electrode for electricity storage devices is provided with: a collector; a first mixture layer that is formed on the surface of the collector and contains a first binder and an active material; and a second mixture layer that is formed on the surface of the first mixture layer and contains a second binder, which has a storage modulus lower than that of the first binder, and an active material. La présente invention se rapporte à une électrode négative pour des dispositifs de stockage d'électricité, ladite électrode négative comprenant : un collecteur; une première couche de mélange qui est formée sur la surface du collecteur et contient un premier liant et un matériau actif; et une seconde couche de mélange qui est formée sur la surface de la première couche de mélange et contient un second liant, qui présente un module de conservation qui est inférieur à celui du premier liant, et un matériau actif.
