摘要：
The present invention provides a silicone resin composition for an optical semiconductor device, comprising(A) 100 parts by mass of an organopolysiloxane having a weight average molecular weight of from 500 to 20000, reduced to polystyrene, and represented by the following average compositional formula (1), (CH3)aSi(OR1)b(OH)cO(4-a-b-c)/2 (1) wherein R1 is an organic group having 1 to 4 carbon atoms and a, b, and c are numbers satisfying the equations: 0.8≦a≦1.5, 0≦b≦0.3, 0.001≦c≦0.5, and 0.801≦a+b+c
