An object of the present invention is to provide a method for producing a dioxolane compound having high purity and high yield and low skin irritation, and an ultraviolet curable composition. The formula (I): Embedded image (R 1 and R 2 are hydrogen, an alkyl group having 1 to 18 carbon atoms or a phenyl group) and glycerin are dehydrated in the presence of an esterification catalyst while the conversion of glycerin is 20 to 95%. After the reaction is completed, the glycerin layer is removed from the reaction solution. Embedded image (Wherein R 1 and R 2 are the same as described above): a methanol derivative represented by the formula (II) and a lower alkyl (meth) acrylate, a transesterification catalyst and Formula (III) reacted in the presence of a polymerization inhibitor: Embedded image (Wherein R 1 and R 2 are the same as above; R 3 is hydrogen or a lower alkyl group having 1 to 4 carbon atoms); and a compound represented by the formula (III) and a polyfunctional monomer: UV curable composition containing a monomer component and a photopolymerization initiator.
