A non-aqueous electrolyte secondary cell having a high cycle characteristic and excellence in continuous charging characteristic at high potential is provided. The non-aqueous electrolyte secondary cell comprises a positive electrode having a positive electrode active material, a negative electrode having a negative electrode active material, and a non-aqueous electrolyte having a non-aqueous solvent and electrolytic salt. The positive electrode contains lithium phosphate. The non-aqueous solvent contains a halogenated ethylene carbonate compound represented by chemical formula 1: where W, X, Y, and Z independently represent a halogen or a hydrogen atom, at least one selected from W, X, Y, and Z being a halogen.
