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: [R<SUP>1</SUP><SUB>3</SUB>SiO<SUB>1/2</SUB>]<SUB>a </SUB>[R<SUP>2</SUP><SUB>2</SUB>SiO<SUB>2/2</SUB>]<SUB>b </SUB>[R<SUP>3</SUP>SiO<SUB>3/2</SUB>]<SUB>c </SUB>(where R<SUP>1</SUP>, R<SUP>2</SUP>, and R<SUP>3 </SUP>are univalent organic groups, at least two of which are contain epoxy groups and are free of aromatic rings; more than 20 mole % of R<SUP>3 </SUP>are aryl groups; a+b+c & equals; 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 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.
