A polyorganometallosiloxane comprising a metalloxy unit represented by general formula (1): M1Ox/2 (where M1 is an atom of group 4 A or group 5 A of the periodic table, and "x" is the valency of M1), a metalloxy unit represented by general formula (2): M2Oy/2 (where M2 is an atom of group 2 A or group 2B of the periodic table, and "y" is the valency of M2), and an organosiloxane unit represented by general formula (3): R1aSiO(4-a)/2 (where R1 is an alkyl group, an alkenyl group, a phenyl group, an aralkyl group, or a hydrogen atom, and "a" is a number satisfying: 0 < a < 3), and a curable polymer composition which contains this polyorganometallosiloxane and is cured by a hydrosilylation reaction to form a cured product with a high refractive index, high visible light transmittance, and excellent heat resistance and moisture resistance.
