Abstract
A silicone resin sheet is formed from a resin composition containing a thermosetting silicone resin and microparticles. The complex viscosity thereof at a frequency of 10 Hz is 80 to 1000 Pa·s and the tan δ thereof at a frequency of 10 Hz is 0.3 to 1.6 obtained by a dynamic viscoelastic measurement at a frequency of 0.1 to 50 Hz at 30° C.; a rate of frequency increase of 10 Hz/min; and a distortion of 1% in a shear mode.
