A biological material assay instrument is disclosed, including a rotating body and a main body, the rotating body including one or more cartridge holders having a cartridge in which a reagent and an analyte in a sample react, and the main body including an optical assay At least a pair of light-emitting portion and light-receiving portion of the analyte, the rotating body further includes a light-emitting optical waveguide for guiding light of the light-emitting portion to the light-irradiated surface and a light guide for passing through the light-receiving measurement surface The light-receiving optical waveguide led to the light-receiving portion, the light-irradiating surface is one surface of the cartridge other than the sample inflow surface into which the sample flows and the centrifugal force applying surface into which the centrifugal force is applied by the rotation of the rotating body The surface separates particulate components in the sample from the sample and is adsorbed to and deposited on the centrifugal force applying surface, which is a surface other than the sample inflow surface and the centrifugal force applying surface. |
