The present invention relates to a nonaqueous electrolyte secondary battery comprising
an anode capable of doping with and dedoping from lithium, a cathode and a nonaqueous
electrolyte. The anode includes a carbon material, a polymer material and an Sn-containing
compound expressed by a below general formula (1).
(In the formula, M1 designates at least one kind of material selected
from Co and Cu, and M2 designates at least one kind of material selected
from Cr, Fe, Mn, Nb, Mo, W, B and P. M3 designates at least one kind
of material selected from In, Ag, Zn and Al. x, y, and z are respectively represented
by 0.1
