A polymerizable silane compound that yields a cured product exhibiting a high refractive index and a low Abbe number, used in a polymerizable composition for preparing a molded article having higher transparency. A polysiloxane being a polycondensation product of the compound of formula [1]:
(wherein X is a phenyl group having at least one substituent having a polymerizable double bond, a naphthyl group having at least one substituent having a polymerizable double bond, a biphenyl group having at least one substituent having a polymerizable double bond, or a phenanthryl group having at least one group having a polymerizable double bond, Ar
1
is a condensed polycyclic hydrocarbon group (optionally substituted with a C
1-6
alkyl group), or a hydrocarbon ring assembly group wherein two or more aromatic rings are directly bonded through a single bond (optionally substituted with a C
1-6
alkyl group), and R
1
is a methyl, ethyl, or isopropyl group).
