The objective of the invention is to provide an electrolyte solution with which an electrochemical device or module having excellent storage characteristics in high temperatures can be obtained. The invention discloses an electrolyte solution including a solvent and an electrolyte salt, said electrolyte solution being characterized by including at least one compound (alpha) selected from the group consisting of an amine (A) represented by a general formula (A) and an amide (B) represented by a general formula (B), wherein the content of the compound (alpha) in the electrolyte solution is 0.001-20ppm. In the formula (A), R1 and R2 can be the same or different, and are C1-7 alkyl groups, and Rf1 is a C1-7 fluorinated alkyl group. In the formula (B), R3, R4, and R5 can be the same or different, and are C1-7 alkyl groups.
