Provided is an addition-curable silicone composition having little shrinkage or change in hardness due to heat, a cured silicone product of which obtained has excellent adhesiveness and appearance and makes it possible to protect metals, especially silver, from corrosion. An addition-curable silicone composition containing 100 parts by mass of polyorganosiloxane having an alkenyl group, polyorganohydrogensiloxane in an amount to make 0.9-3.0 mol of hydrogen atoms bonded to silicon atoms per 1 mol total amount of this alkenyl group, a catalytic amount of hydrosilylation catalyst, 0.01-10 parts by mass of adhesiveness-imparting agent, and 0.001-0.015 parts by mass, calculated in terms of metal atoms, of carboxylic acid metal salt indicated by (R 3 COO) k M (M indicates a metal atom selected from Ce, Fe, Cr, La, Nd, Pr, and Sm, k indicates a positive number of 2-4, and R 3 indicates a substituted or unsubstituted hydrocarbon group having 4-10 carbon atoms). |
