To provide a radiation-curable composition which can provide a cured product capable of sufficiently satisfying all of light resistance, transparency and curability and therefore can be useful in much more applications in addition to optical members, lighting members, and automobile members. A radiation-curable composition used after cured by radiation energy, wherein a cured product produced by curing the curable composition by radiation energy of 2J/cm 2 satisfies: an initial light transmittance of 80% or more at a wavelength of 380 nm, and a light transmittance retention of 90% or more after 200 hours of accelerated light resistance test.
