PROBLEM TO BE SOLVED: To provide electrolyte for a nonaqueous power storage device which operates in a wide voltage region, has a high cycle life, and produces little gas, by improving permeability of the electrolyte to a positive electrode.SOLUTION: This electrolyte for the nonaqueous power storage device contains a compound (A) in which at least one of hydrogen atoms of acid selected from a group comprising protonic acid having a phosphorus atom and/or a boron atom, sulfonic acid and carboxylic acid is substituted by a substituent expressed by the formula (1) and a lithium compound (B) containing a fluoroalkyl group, and the content of the lithium compound (B) containing the fluoroalkyl group is 100-5,000 ppm with respect to the mass of the nonaqueous power storage device. In the formula (1), R-Rare organic groups of C1-10 which may be independently substituted. |
