PROBLEM TO BE SOLVED: To provide a polysiloxane-based composition excellent in heat resistance, light resistance, adhesiveness to substrates, and cohesiveness. SOLUTION: The polysiloxane-based composition comprises a polyhedral structure polysiloxane obtained by modifying a polyhedral structure polysiloxane-based compound (a) containing alkenyl groups and/or hydrosilyl groups with a compound (b) having a hydrosilyl group and/or an alkenyl group and capable of hydrosilylation-reacting with the component (a), a curing agent, a hydrosilylation catalyst, and a polysiloxane having epoxy groups and hydrosilyl groups in the molecule.
