Abstract
The present invention provides a polysiloxane composition maintaining high transparency over a wide wavelength region and a wide temperature region and being excellent in heat resistance, low-dielectric characteristics, workability, and the like. A polysiloxane composition includes (A) a polysiloxane which is composed of a polysiloxane compound having a polyhedral skeleton having 6 to 24 Si atoms in its molecule and which has at least one alkenyl group bonded directly or indirectly to a Si atom constituting the polyhedral skeleton, (B) a polysiloxane having a hydrosilyl group, and (C) a hydrosilylation catalyst.
