The present invention relates to a nonaqueous electrolyte secondary battery which is provided with: a positive electrode plate in which a positive electrode mixture layer containing a positive electrode active material is formed on a positive electrode collector; a negative electrode plate in which a negative electrode mixture layer containing a negative electrode active material is formed on a negative electrode collector; a separator; a nonaqueous electrolyte; an outer casing can; and a sealing body. This nonaqueous electrolyte secondary battery is configured such that: the positive electrode plate and the negative electrode plate are wound together with the separator being interposed therebetween; the positive electrode active material contains a lithium nickel composite oxide that contains cobalt and aluminum as constituent elements; the negative electrode active material contains graphite and a silicon material; the negative electrode plate has negative electrode collector exposed portions, where a negative electrode active material layer is not formed, at both ends in the longitudinal direction; and negative electrode tabs are respectively connected to the negative electrode collector exposed portions.
