1. An apparatus for producing a non-aqueous electrolytic solution comprising:
an ion exchange unit accommodating a weakly basic anion exchange resin through which an alkali metal salt electrolyte-containing solution having the alkali metal salt electrolyte dispersed in a carbonate ester is passed to obtain the non-aqueous electrolytic solution,
wherein the weakly basic anion exchange resin has a styrene-based resin as substrate and a tertiary amino group as weakly basic anion exchange group, and has a total ion exchange capacity of 0.1 to 3.0 eg/L-R before treatment of the alkali metal salt electrolyte-containing solution.
