PURPOSE: An anode and a secondary battery are provided to improve current collection property by obtaining enough conductive paths between plural anode active materials by plural metal fiber. CONSTITUTION: A secondary battery includes a cathode(21), an anode(22) and electrolyte. The anode comprises plural metal fiber and plural anode active material particles. The plural metal fiber forms a retina structure of 3D. At least part of plural metal fiber is connected with one another and forms retina structure of 3D. The plural anode active material particles have silicon. |
