The non-aqueous electrolyte secondary cell according to an embodiment of the present invention is provided with a positive electrode having a positive electrode mixture layer, as well as a negative electrode and a non-aqueous electrolyte. The positive electrode mixture layer contains a phosphoric acid compound and a lithium transition metal oxide containing zirconium (Zr), and the non-aqueous electrolyte contains a chain carboxylic acid ester. This configuration makes it possible to provide a non-aqueous electrolyte secondary cell having excellent low-temperature output characteristics. Accordingly, this invention is suitable for application as a drive power source for mobile information terminals such as, for example, portable telephones, laptop computers, smartphones, and tablet terminals, where a particularly high energy density is required. Also envisaged is use in high output applications such as electric vehicles (EV), hybrid electric vehicles (HEV), and power tools.
