Abstract
In an electric device the negative electrode active material layer includes a silicide phase containing a silicide of a transition metal is dispersed in a parent phase containing amorphous or low crystalline silicon as a main component, a predetermined composition, and a ratio value (B/A) of a diffraction peak intensity B of a silicide of a transition metal in a range of 2θ=37 to 45° to a diffraction peak intensity A of a () plane of Si in a range of 2θ=24 to 33° in a predetermined range in an X-ray diffraction measurement using a CuKα1 ray is used as a Si-containing alloy. A solid solution or an oxide-coated solid solution in which a coating layer containing an oxide in a predetermined amount is formed on the particle surface of the solid solution and is used in the positive electrode active material layer.
