Summary: | PROBLEM TO BE SOLVED: To prevent deformation of anode collectors of nonaqueous electrolyte secondary batteries using silicon or silicon oxide as an anode active material to reduce fraction defective. SOLUTION: The nonaqueous secondary battery comprises a cathode, an anode, and a nonaqueous electrolyte. The anode is an active material layer supported on a collector, and the active material layer contains silicon oxide expressed by the formula SiOx, where 0<x<2. Provided that the average composition of SiOx in all of the active material layer is x=xavand composition of SiOx of the active material layer near the collector is x=xB, it is characterized by satisfying the relationship xB>xav.
