[0002] [SOLUTION TO PROBLEM] The negative electrode for an electric device includes: a current collector; and an electrode layer containing a negative electrode active material, an electrically-conductive auxiliary agent and a binder and formed on a surface of the current collector. The negative electrode active material is a mixture of a carbon material and an alloy represented by the following formula (1): SiZnMA...(1) (in formula (1), M is at least one of metal selected from the group consisting of V, Sn, Al, C, and combinations thereof, A is inevitable impurity, and x, y, z and a represent mass percent values and satisfy 0 < x < 100, 0 < y < 100, 0 < z < 100, and 0 ≤ a < 0.5, and x + y + z + a = 100).",
