PROBLEM TO BE SOLVED: To provide a self-adhesive addition reaction-curable silicone composition which has excellent adhesiveness and is useful as an adhesive for optical devices or optical parts. SOLUTION: This self-adhesive addition reaction-curable silicone composition comprises (A) 100 pts. mass of a liquid or solid organopolysiloxane having a viscosity of ≥10 mPa at 25°C, (B) 2 to 100 pts. mass of an organohydrogenpolysiloxane which has at least two SiH groups, has a viscosity of ≤1,000 mPa sec at 25°C, and has a SiH group-containing bifunctional siloxane unit number rate of ≤50% based on the total number of the bifunctional siloxane units contained in one molecule, (C) a straight chain or cyclic organohydrogenpolysiloxane main component having the above-mentioned rate of <50% in a contained SiH group molar ratio of 0.05 to 1 to the SiH groups contained in the component (B), and (D) an effective amount of an addition reaction catalyst.
