A curable silicone composition includes: (A) an organopolysiloxane represented by the siloxane unit formula (1) given below and having at least two univalent organic groups that contain epoxy groups and are free of aromatic rings: [R13SiO1/2]a [R22SiO2/2]b [R3SiO3/2]c (where R1, R2, and R3 are univalent organic groups, at least two of which are univalent organic groups which contain epoxy groups and are free of aromatic rings; more than 20 mole % of R3 are aryl groups; a + b + c = 1; on average, 'a' satisfies the following condition: 0 ≤ a ≤ 0.8; on average, 'b' satisfies the following condition: 0 ≤ b ≤ 0.8; and, on average, 'c' satisfies the following condition: 0.2 ≤ c ≤ 1.0); (B) a linear-chain organopolysiloxane having at least two univalent organic groups that contain phenolic hydroxyl groups; and (C) a curing accelerator. |
