Abstract
In a concentration measuring device, a measuring light in a wavelength region where an absorbance related to the water in a subject can be practically ignored is irradiated to the subject by a light source. The transmitted light transmitted through the subject is received in a light receiving part. An optical rotation calculation part calculates an optical rotation of the subject by using an output signal from the light receiving part, and an absorbance calculation part calculates an absorbance of the subject by using an output signal from the light receiving part. A concentration calculation part calculates a concentration of glucose by using a glucose measurement data related to an aqueous solution of simple glucose, a protein measurement data related to an aqueous solution of simple protein, the optical rotation calculated by the optical rotation calculation part, and the absorbance calculated by the absorbance calculation part.
