摘要： The present invention provides a non-aqueous electrolyte secondary battery wherein a reaction between a non-aqueous electrolyte and an electrode is suppressed and decrease in battery capacity under high temperature is restricted, so that long time excellent battery characteristics can be obtained. A non-aqueous solvent of the non-aqueous electrolyte contains: chain fluorinated carboxylic acid ester represented by the formula R1-CH2—COO—R2 where R1 represents hydrogen or alkyl group and R2 represents alkyl group and the sum of the carbon numbers of R1 and R2 is 3 or less, and in the case that R1 is hydrogen, at least one part of hydrogen in R2 is replaced with fluorine, and, in the case that R1 is alkyl group, at least one part of hydrogen in R1 and/or R2 is replaced with fluorine; and a film forming chemical compound decomposed in the range of +1.0 to 3.0 V based on an equilibrium potential between metal lithium and lithium ion.
