A polyorganometallosiloxane comprising a metalloxy unit represented by general formula (1): M1Ox/2 (where M1 is an atom of group 4A or group 5A 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 2A 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.
