Provided is an addition-curable silicone composition in which the obtained silicone cured product has excellent adhesiveness and appearance, and is less susceptible to heat shrinkage and hardness change. (A) 100 parts by mass of an alkenyl group-containing polyorganosiloxane, (B) 0 mol of hydrogen atoms bonded to silicon atoms with respect to 1 mol of the total amount of alkenyl groups of the component (A) .9 to 3.0 mol, (C) catalyst amount of hydrosilylation reaction catalyst, (D) 0.01 to 10 parts by mass of adhesion-imparting agent, and (E) organic free radical (5 or 6 members) The addition-curable silicone composition containing 0.001 to 0.05 parts by mass of a compound having a nitrogen-containing heterocyclic skeleton, wherein the nitrogen is bonded to an oxygen atom having a free radical. |
