PROBLEM TO BE SOLVED: To provide: an addition curable silicone composition which exhibits a low viscosity, preferable curability, a large refractive index, a high light transmittance, preferable adhesion to a substrate, crack resistance, and a low gas permeability; and a semiconductor apparatus comprising a semiconductor element subjected to cured coating with the composition.SOLUTION: The addition curable silicone composition contains: (A) an organopolysiloxane represented by the unit formula (1) defined by (RSiO)(RSiO)(RSiO)(XO); (B) an organopolysiloxane represented by the unit formula (2) defined by (RSiO)(RSiO)(RSiO)(XO); and (C) an organohydrogenpolysiloxane represented by the specified general formula (3) and having at least two Si-H bonds in a molecule. The content of component (C) is 1-200 pts.mass relative to the summed content 100 pts.mass of (A) and (B) components. |
