PROBLEM TO BE SOLVED: To provide a biosensor constituted so as to suppress non-specific adsorption with respect to a surface (reference part) holding no physiologically active substance. SOLUTION: In the biosensor comprising a substrate having at least two kinds of surfaces in the same plane, at least one of the surfaces is a surface holding no physiologically active substance and at least two kinds of hydrophilic compounds different in molecular weight are bonded to the surface holding no physiologically active substance.
