PURPOSE: A curable composition is provided to have excellent processability, workability, crack resistance, hardness, heat resistance, and adhesion. CONSTITUTION: A curable composition includes an organopolysiloxane which has a composition represented by chemical formula 1: (R^1R^2_2SiO_1/2)_a(R^3R^4SiO_2/2)_b(R^5SiO_3/2)_c(SiO_2)_d; and an organopolysiloxane which includes a hydrogen atom combined to a silicon atom. In chemical formula 1, R^1 is an epoxy group or a C2 or more monovalent hydrocarbon group; R^2 is an epoxy group or a C1-4 alkyl group; each of R^3 and R^4 is a C1-20 alkyl group, a C2-20 alkenyl group, an epoxy group, or a C6-25 aryl group; R^5 is a C1-20 alkyl group, an epoxy group, ora C6-25 aryl group; each of R^1, R^3, and R^4 is an alkenyl group; each of R^1-R^5 is an epoxy group. |
