A process in which 4-chloro-1,3-dioxolan-2-one as a starting substance is fluorinated with a fluorinating agent. By the process, high-purity 4-fluoro-1,3-dioxolan-2-one can be produced in a short time while maintaining high yield. A fluorinating agent is added to and reacted with 4-chloro-1,3-dioxolan-2-one in an organic solvent in an amount of 1.4 mol or larger per mol of the 4-chloro-1,3-dioxolan-2-one to obtain 4-fluoro-1,3-dioxolan-2-one containing chlorine radicals. Thereafter, an intermediate treatment step is conducted according to need. The 4-fluoro-1,3-dioxolan-2-one containing chlorine radicals obtained is purified by distillation. Thus, 4-fluoro-1,3-dioxolan-2-one reduced in the content of chlorine radicals is produced.
