<P>PROBLEM TO BE SOLVED: To provide an anode which can improve cycle characteristics and provide a battery using the same. <P>SOLUTION: On an anode collector 11 has an anode active substance layer 13 with a conductive adhesive layer 12 between. The conductive adhesive layer 12 is composed of conductive particles and a binding material. A mass ratio of the conductive particles to the binding material is preferably in a range between 70:30 and 95:5. An average particle diameter of the conductive particles is preferably in a range between 0.01 μm or more and 20 μm or less. The anode active substance layer 13 has an amorphous phase containing Si as a component element. Furthermore, the anode active substance layer 13 contains oxygen as a component element and its content is preferably in a range of 5 atom no.% or more and 40 atom no.% or less. <P>COPYRIGHT: (C)2007,JPO&INPIT |
