Abstract
A negative electrode active material for an electric device includes an alloy containing, in terms of mass ratio, 35%≦Si≦78%, 7%≦Sn≦30%, 0%<Ti≦37% and/or 35%≦Si≦52%, 30%≦Sn≦51%, 0%<Ti≦35%, and inevitable impurities as a residue. The negative electrode active material can be obtained with a multi DC magnetron sputtering apparatus by use of, for example, silicon, tin and titanium as targets. An electric device employing the negative electrode active material can keep a high discharge capacity and ensure a high cycle property.
