The present invention provides a curable composition capable of forming a hard coat film having high refractive index, substrate adhesion, light resistance and alkali resistance at the same time. A curable composition includes an organic-inorganic composite (A) in which a silane coupling agent having a (meth) acryloyl group and an alkoxysilyl group and first inorganic oxide fine particles are bonded, and at least 2 The second inorganic which is a kind of inorganic oxide fine particles different from the polyfunctional (meth) acrylate monomer (B) having two (meth) acryloyl groups, the polymerization initiator (C), and the first inorganic oxide fine particles Oxide fine particles (D) are contained in a predetermined ratio. When the zeta potential of the organic-inorganic composite (A) is V1 (mV) and the zeta potential of the second inorganic oxide fine particles (D) is V2 (mV), the ratio V1 / V2 of V1 and V2 is 0. 7 <V1 / V2 <1.5 is satisfied, and both V1 and V2 are −50 (mV) or less.
