PROBLEM TO BE SOLVED: To provide a biological light measuring apparatus capable of measuring and displaying physiological changes of a subject appropriately by a simple procedure and also capable of improving the precision of diagnosis. SOLUTION: This biological light measuring apparatus comprises an optical measuring section and a processing section. The optical measuring section measures light transmitted through the subject using beams of light of a plurality of wavelengths and measures a change in optical intensity of the each wavelength. The processing section calculates and displays a hemoglobin change of the subject using the measured changes in optical intensities and absorption coefficients of hemoglobin, or the like, contained in the subject. In addition, the processing section stores virtual optical characteristics of predetermined biological phenomena, such as changes in arterial blood or changes in scattering characteristics due to nerve activity, or the like. Using the optical intensities measured by the optical measuring section and the virtual optical characteristics, the processing section calculates and displays a change in a predetermined biological phenomenon of the subject.
