摘要： Provided is a contact lens that can exhibit excellent breaking elongation and surface hydrophilicity even when produced using a hydrophobic mold made of polypropylene or the like without performing a surface hydrophilic treatment. Further provided are a monomer composition and a polymer that can be suitably used for obtaining the contact lens. This monomer composition contains (A) a siloxanyl group-containing itaconic acid diester monomer, (B) an amide group-containing monomer, (C) a hydroxy group-containing monomer, (D) a siloxanyl group-containing (meth)acrylate, and (E) a cross-linking agent in a specific ratio.
