A secondary battery capable of providing a high energy density and superior cycle characteristics is provided. The secondary battery includes a cathode, an anode, and an electrolytic solution. The anode has an anode active material layer containing a carbon material and a lithium-containing compound (Li3-aMaN) as an anode active material. M is one or more transition metal elements, a is a numerical value satisfying 0<a<0.8. The average particle diameter of the lithium-containing compound is 1 μm or less |
