PROBLEM TO BE SOLVED: To provide a laminated structure containing a metal thin film, suitable for a chemical/biosensor using surface light reflection and capable of measuring a surface adsorption amount with high sensitivity. SOLUTION: The laminated structure containing the metal thin film for reflection spectrum measurement has the thin metal film formed on a substrate via an intermediate thin film layer. A surface abutting at least the intermediate thin film layer of the substrate and the metal thin film comprises a metal having a light absorption zone in a visible light region. For the intermediate thin film layer, the surface abutting the intermediate thin film layer of the substrate and the metal thin film comprise different materials. A reflection rate of incident light is reduced by multiple reflection between layers of the surface abutting the intermediate thin film layer of the substrate and the metal thin film.
