In a biochemical measuring instrument, each light receiving section (115A-115C) of a photosensor (11) receives infrared light having a wavelength corresponding to a component being measured out of infrared light emitted from a living body. A measurement object temperature sensor (13) and humidity sensor (15) measure the temperature at a part being measured and the humidity in a space between the part being measured and the photosensor, respectively at measuring. In a concentration calculation algorithm (35), output value from each light receiving section (115A-115C) based on the light radiated from the living body is corrected by output values related to the temperature at a part being measured, and the humidity in a space between the part being measured and the photosensor. The other signal intensity is corrected using one signal intensity between correlated signal intensities out of signal intensities from respective light receiving sections (115A-115C) thus calculating the concentration of the component. |
