PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte secondary battery including an electrode active material that contains Na<SB POS="POST">1+x</SB>MnPO<SB POS="POST">4</SB>F<SB POS="POST">x</SB>and capable of being charged and discharged. SOLUTION: A nonaqueous electrolyte secondary battery according to the present invention includes an electrode active material capable of reversibly absorbing and desorbing sodium. The electrode active material has a tabular particle shape and is represented by a compositional formula: Na<SB POS="POST">1+x</SB>MnPO<SB POS="POST">4</SB>F<SB POS="POST">x</SB>(in the formula, x satisfies 0<x≤1).
