A curable composition having excellent curability, a high refractive index, and excellent adhesion to a transparent sheet substrate, particularly a methacrylic transparent sheet substrate, preferably an active energy ray-curable composition, more preferably Provide an active energy ray-curable composition suitable for manufacturing optical articles. A curable composition containing (meth) acrylate (A) and urethane (meth) acrylate (B) represented by the following general formula (1). Embedded image [However, in the formula (1), R 1 and R 2 each independently represent a hydrogen atom or a methyl group, and R 3 represents an alkylene group which may have a hydroxyl group. n represents an integer of 1 to 10, and a represents an integer of 1 or 2. ] [Selection diagram] None |
