PROBLEM TO BE SOLVED: To provide an organo-polysiloxane composition of liquid state that can be crosslinked by non-platinum metal-based catalyst and that can produce a cured article having excellent heat resistance and light stability.SOLUTION: Provided is an organo-polysiloxane composition containing (A) an organo-polysiloxane represented by an average composition formula (1) and (B) a setting catalyst. (RRSiO)(RSiO)(RSiO)(1). (Ris a group represented by formula (2); Ris a saturated aliphatic hydrocarbon group, aromatic hydrocarbon group or alkoxy group; and Ris a saturated aliphatic hydrocarbon group, aromatic hydrocarbon group or alicyclic hydrocarbon group). |
