ABSTRACT:
An object of the present invention is to provide a negative electrode for a secondary battery which has large capacity and restrains a rise in resistance inside the battery and reduction in capacity even after cycles and the secondary battery using the same. A first active material layer2acomprising members occluding and releasing Li onto a collector1ais formed and a second active material layer3aas an alloy layer containing metal forming alloy with lithium or lithium and metal not-forming alloy with lithium is formed thereon. The secondary battery is constituted using the negative electrode.
