An object of the present invention is to provide a polymerizable resin composition in which the cured product has a high refractive index and a viscosity at a high shear force is not more than a certain value. (A1) S-containing epoxy resin represented by the following general formula, (A2) an epoxy compound having a softening point of 70 ° C. or lower, (B) a curing accelerator, and (C) two or more in one molecule An epoxy polymerizable composition comprising a thiol compound having a thiol group and having a viscosity of 100 to 15000 mPa · s at 25 ° C. and 60 rpm measured with a B-type viscometer. In the general formula, A 1 and A 2 each independently represent a benzene ring or a 1,3,5-triazine ring, and X 11 each independently represents —S—, —SO 2 —, —O—, —C. (R 21 ) 2 — (R 21 is independently a hydrogen atom or an alkyl group having 1 to 3 carbon atoms), Y 11 and Y 12 are each independently —O— or —S—, Z 1 and Z 2 each independently represent —O— or —S—.
