To provide a polymerizable composition capable of forming a thick hydrophilic resin coating having high hardness and excellent durability on the surface of an object to be treated, which is a surface treatment object, and a hydrophilizing treatment method in which the polymerizable composition is used. In a polymerizable composition including a polymerizable compound (A), a polymerization initiator (B), inorganic fine particles (C) and a solvent (S), a polymerizable betaine compound (A1) having an ethylenic unsaturated double bond and a betaine structure and an adhesive polymerizable compound (A2) having an ethylenic unsaturated double bond and a specific type of adhesive group are used as the polymerizable compound (A); a water-soluble radical polymerization initiator (B1) is used as the polymerization initiator (B); and inorganic fine particles (C) having a functional group capable of forming a covalent bond with a polymer of the polymerizable compound (A) are used.
