PROBLEM TO BE SOLVED: To provide a curable composition having a low viscosity and good workability, which can form a cured product having a low curing shrinkage during polymerization and a low hygroscopic property. A reaction product (A) of polyolefin glycol (a1) and (meth) acryloyloxyalkyl isocyanate (a2), and an alicyclic (meth) acrylate (B) represented by the following formula (1) are contained. A curable composition. [Chemical 1] (In the formula, R 1 represents an organic group having 1 to 20 carbon atoms. R 2 represents a direct bond, an alkylene group or a polyoxyalkylene group having 1 to 8 carbon atoms. R 3 represents a hydrogen atom or a methyl group. Α represents an integer of 1 to 11.
