A biosensor chip includes a substrate, a polymer having an anionic functional group and being arranged on a surface of the substrate, a polyamino group which is directly or indirectly bound to the anionic functional group at a surface of the polymer, and a long-chain alkyl-based group which is directly or indirectly bound to the anionic functional group at the surface of the polymer. Therefore, the biosensor chip can immobilize a bioactive material on the surface of the biosensor chip without influence of electric charge repulsion.
