Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a polysiloxane composition exhibiting particularly high heat resistance and excellent moldability. SOLUTION: The polysiloxane composition in the state of a flowable liquid or a solid comprises at least one component [A] and at least one component [B]: R1SiO3/2 [A]; and R2R3SiO2/2 [B] [wherein R1, R2and R3may be the same or different and are each either a hydrocarbon group or a hydrocarbon group containing an aromatic ring]. In the polysiloxane composition, viscosity can be controlled by heating to such a level as to permit various operations such as molding, application, or blending with solid components except the components [A] and [B], and then the resulting viscosity-controlled polysiloxane composition can be converted into a cured product through high-temperature heat treatment.
