The present invention provides a copolymer having a wrinkle structure in the main chain and a curable resin composition containing the copolymer. SOLUTION: General formula (1) Y- [Z- (O 1/2 -R 2 2 SiO 1/2 ) a- (R 1 SiO 3/2 ) n- (O 1/2 ) b ] m- Z—Y [R 1 and R 2 are vinyl group, alkyl group, phenyl group, (meth) acryloyl group, allyl group or group having an oxirane ring, Z is the following general formula (2) Y is any one of the following (3) to (5). (3) [(R 4 O) R 2 2 SiO 1/2 ] a- [R 1 SiO 3/2 ] n- [O 1/2 ]-(4) [R 4 O 1/2 ] b- [ R 1 SiO 3/2] n - [ O 1/2 -R 2 2 SiO 1/2] - (5) (R 4 O 1/2) - (6) (R 2 3 SiO 1/2) - ( R 4 is a cage structure-containing curable silicone copolymer having a structural unit represented by a hydrogen atom, a methyl group or an ethyl group)}.
