    Abstract: An inspecting instrument to be used for measuring, using a test substance-containing solution containing a test substance and a liquid, which is contained in the test substance-containing liquid. The inspecting instrument includes a wall that has a periodic structure resulting from a plurality of recesses or protrusions, the plurality of recesses or the plurality of protrusions including a refractive index adjusting layer on surfaces thereof, the refractive index adjusting layer being a layer having a refractive index greater than a refractive index of the test substance-containing solution or being a silicon layer. A method of measuring the concentration of a test substance in a liquid, measured using the inspecting instrument, has high accuracy.
