Abstract

The present invention provides a condensation-curable silicone resin composition sheet that is in a plastic solid state or a semi-solid state at ordinary temperature, including: (A) organopolysiloxane having a weight average molecular weight of 5,000 or more and 1,000,000 or less in terms of polystyrene shown by the following formula (1): (R 1 3 SiO 1/2 ) a' (R 1 2 SiO 2/2 ) b' (R 2 SiO 3/2 ) c' (SiO 4/2 ) d' (OR 3 ) e' (1) ; together with (B) organopolysiloxane having a molecular weight of 10,000 or more and 1,000,000 or less in terms of polystyrene shown by the following formula (2): (R 1 3 SiO 1/2 ) a (R 1 2 SiO 2/2 ) b (R 2 SiO 3/2 ) c (SiO 4/2 ) d (OR 3 ) e (HSi(OR 3 ) 2 O 1/2 ) f (2) in an amount of 5 to 100 parts by mass based on 100 parts by mass of the component (A). This condensation-curable silicone resin composition sheet is easy to be handled and has high heat resistance and ultraviolet light resistance while being excel in curing characteristics.
