  A process for producing a carbonic acid ester is provided, the process comprising a step of synthesizing a saturated alkyl carbonic acid ester represented by Formula (1) so as to give the saturated alkyl carbonic acid ester represented by Formula (1) as a crude product and a step of subjecting the crude product to liquid-liquid extraction using a saturated hydrocarbon solvent and a solvent comprising an organic solvent that is not infinitely miscible with the saturated hydrocarbon solvent so as to give the saturated alkyl carbonic acid ester represented by Formula (1) as a purified product (in Formula (1), R 1 and R 2 independently denote a saturated hydrocarbon group provided that the sum of the number of carbons in R 1 and the number of carbons in R 2 is at least 12 but no greater than 50). There are also provided a carbonic acid ester produced by the production process, and a magnetic recording medium comprising a non-magnetic support and, above the non-magnetic support, a magnetic layer comprising a ferromagnetic powder dispersed in a binder, the magnetic layer comprising the carbonic acid ester and having on the surface a number of protrusions that satisfies Formula (2) 0.01≦H 15 /H 10 <0.20   (2) (H 10 denotes the number of protrusions per unit area on the surface of the magnetic layer that have a height of less than 10 nm (number/μm 2 ), and H 15 denotes the number of protrusions per unit area on the surface of the magnetic layer that have a height of 15 nm or greater (number/μm 2 )).
