摘要： A non-aqueous electrolyte secondary battery of the present invention includes: a positive electrode in which an olivine-type compound is used as a positive electrode active material; a negative electrode in which amorphous-based carbon is used as a negative electrode active material; a separator sandwiched between the positive electrode and the negative electrode; a non-aqueous electrolyte; and a casing which houses the positive electrode, the negative electrode, the separator, and the non-aqueous electrolyte. The positive electrode, the negative electrode, and the non-aqueous electrolyte are configured to satisfy an inequality: (Rn/(Rp+Rn))≤0.54, where Rp is a positive electrode internal resistance attributed to both the positive electrode and a positive electrode reaction during charging of the secondary battery, Rn is a negative electrode internal resistance attributed to both the negative electrode and a negative electrode reaction during charging of the secondary battery, and (Rp+Rn) is an inter-terminal internal resistance of the secondary battery during charging of the secondary battery.
