1. A curable silicone composition comprising:
(A) an alkenyl group-containing organopolysiloxane having at least two alkenyl groups per molecule;
(B) an organohydrogenpolysiloxane having at least two silicon atom-bonded hydrogen atoms per molecule;
(C) an epoxy group-containing resinous organopolysiloxane represented by Average Unit Formula (I):
(R13SiO1/2)f(R22SiO2/2)g(R1SiO3/2)h(SiO4/2)i(XO1/2)j
wherein, in Formula (I),
R1 are, in each case, independently halogen-substituted or unsubstituted monovalent hydrocarbon groups, wherein at least two R1 are alkenyl groups;
R2 are, in each case, independently halogen-substituted or unsubstituted monovalent hydrocarbon groups or epoxy group-containing organic groups, wherein at least one R2 is an epoxy group-containing organic group;
X is a hydrogen atom or an alkyl group;
0≤f<1; 0<g<1; 0≤h<0.9; 0≤i<0.5;
0<j<0.5; f+g+h+i+j=1.0; h+i>0; and
j/(f+g+h+i+j)>0.05}; and
(D) a curing catalyst.
