Abstract: The present invention aims to provide a polysiloxane composition which exhibits high heat and light resistance, and excellent gas-barrier properties. The polysiloxane composition of the present invention includes: (A) a modified polyhedral polysiloxane which is obtained by modifying (a) an alkenyl group-containing polyhedral polysiloxane compound with (b) a hydrosilyl group-containing compound; and (B) an organopolysiloxane containing at least two alkenyl groups in a molecule, wherein the polysiloxane composition after curing has a water vapor permeability of not more than 30 g/m2/24 h, and the polysiloxane composition includes (B1) an aryl group-containing organopolysiloxane as the organopolysiloxane (B), and/or (C) a component which is (C1) an organosilicon compound that contains one alkenyl or hydrosilyl group in a molecule, or (C2) a cyclic olefin compound that contains one carbon-carbon double bond in a molecule.
