The present invention provides an ionic liquid that can widely be used as materials of various electrical devices and solvents for various reactions and that exhibits hydrophobicity causing phase separation from water, and a process for producing the ionic liquid. The ionic liquid contains at least one anion selected from the group consisting of a fluoroalkylsulfate anion, a fluorocycloalkylsulfate anion, and a fluorobenzylsulfate anion and exhibits hydrophobicity causing phase separation from water. The halide ion concentration of the ionic liquid may be 70 ppm or less.
