An object of the present invention is to provide a polyorganosilsesquioxane which has high surface hardness and heat resistance by curing, and is capable of forming a cured product excellent in flexibility and workability. The present invention relates to a resin composition comprising a structural unit represented by the following formula (1) and having a molar ratio of a structural unit represented by the following formula (I) to a structural unit represented by the following formula (II) Of the structural unit represented by the following formula (1) and the structural unit represented by the following formula (4) with respect to the total amount (100 mol%) of the siloxane structural unit , The ratio is 55 to 100 mol%, the number average molecular weight is 1000 to 3000, and the molecular weight dispersion degree (weight average molecular weight / number average molecular weight) is 1.0 to 3.0. |
