An anode for a secondary battery is provided to impart improved cycle characteristics during repeated charge/discharge cycles by preventing a drop in discharge capacity caused by deposition of an irreversible coating layer of lithium oxide. An anode(22) comprises: an anode active material layer(22B) comprising an anode active material having silicon(Si) as a constituent; and a coating layer(22C) coated on the anode active material layer and comprising at least one oxide of a 3d transition metal element selected from iron(Fe), cobalt(Co) and nickel(Ni). The oxide is a compound represented by the formula of MxOy, wherein M represents iron, cobalt or nickel, x is an integer of 1-3, and y is an integer of 1-4. |
