An object of the present invention is to provide a curable resin composition which has excellent gas barrier properties, heat resistance and light resistance, and forms a cured product having a low tack. A curable resin composition comprising the following components (A), (B), and (C). (A): The following average unit formula: [R 1 is alkyl, aryl, alkenyl or the like, and the ratio of alkyl to the total amount of R 1 is 50 to 98 mol%, the proportion of aryl is 1 to 50 mol%, and the proportion of alkenyl is 1 to 35 mol%. and a polyorganosiloxane expressed by a1> 0, a2> 0, a3≥0, a4> 0, 0.5≤a1 / a2≤10, a1 + a2 + a3 + a4 = (B): The following average composition formula: [R 2 is alkyl, or aryl. 0.7? M? 2.1, 0.001? N? 1.0, 0.8? M + n? 3] (C): hydrosilylation catalyst |
