description PROBLEM TO BE SOLVED: To accurately measure biological information under an environment such as the outdoors in which extraneous light varies without being affected by the extraneous light. SOLUTION: The measuring device comprises an LED 1022a and an LED 1022b for irradiating different light with two wavelengths to an organic tissue including the arterial blood flow, a photodetector 1024 for receiving the different light with two wavelengths having been absorbed in the organic tissue, and a CPU 130 for calculating the biological information based on the absorbance of each light with different wavelength indicated as the result of the light receiving of the photodetector 1024. The wavelengths of the LEDs 1022a and 1022b belong in the range of wavelength from about 400 nm to about 700 nm. COPYRIGHT: (C)2005,JPO&NCIPI
