A surface enhanced Raman spectrometry apparatus is constituted by: a transparent substrate; a metal member that causes surface enhanced Raman scattering to occur, formed on a surface of the transparent substrate; a pressing mechanism that presses a sample placed in contact with the metal member against the metal member; a measuring light irradiating optical system that irradiates a measuring light beam onto the sample through the transparent substrate; and a light detecting section that spectrally detects Raman scattered light, which is generated when the measuring light beam is irradiated onto the sample, through the transparent substrate.
