Beschreibung
Zusammenfassung:	The present invention is characterized in that, in a negative electrode for lithium-ion secondary battery, the negative electrode being manufactured via an application step of applying a binder resin and an active material onto a surface of collector, the binder resin is an alkoxysilyl group-containing resin that has a structure being specified by formula (I); and the active material includes a lithium-inactive metal that does not form any intermetallic compounds with lithium, or a silicide of the lithium-inactive metal, and an elemental substance of Si. It is possible to upgrade cyclic characteristics by means of using the negative electrode for lithium-ion secondary battery according to the present invention. wherein "R1" is an alkyl group whose number of carbon atoms is from 1 to 8; "R2" is an alkyl group or alkoxyl group whose number of carbon atoms is from 1 to 8; and "q" is an integer of from 1 to 100.
