<p>[Problems to be Solved] To achieve a measurement with an improved signal-to-noise ratio in a measurement method in which an optical enhancement effect of localized plasmon is used to enhance and detect weak light generated from a subject. [Means for Solving the Problems] Performing a measurement using an optical field enhancement device (1) which includes a transparent substrate (10) having a transparent fine uneven structure (22) on a surface and a metal film (24) formed on a surface of the fine uneven structure on the surface of the substrate, in which a subject (S) is placed on the metal film (24) of the optical field enhancement device (1), then excitation light (L1) is projected onto an area of the optical field enhancement device (1) on which the subject (S) is placed, and light generated by the projection of the excitation light (L1) is detected from a back surface side of the transparent substrate (10).</p> |
