Disclosed is an ion-conductive material which comprises an ionic liquid and can realize a higher level of safety. Also disclosed is an electrochemical device using the ion-conductive material. Further disclosed is a method for manufacturing an electrochemical device. An ion-conductive material comprising an ionic liquid satisfying the following conditions: the ionic liquid comprises two or more types of anion, such that at least one type thereof is an anion having a structure in which one or more electron-withdrawing groups are bonded to a central atom having one more non-covalent electron pairs; and the ionic liquid has a maximum exothermic heat-flow peak height no greater than 2 W/g as measured by DSC (measurement temperature range: ordinary temperature to 500° C., rate of temperature rise: 2° C./minute). Preferably, the ion-conductive material comprises an ionic liquid having a gross calorific value of no greater than 1000 J/g as measured by the DSC.
