PROBLEM TO BE SOLVED: To provide a biological information measuring apparatus capable of noninvasively and highly accurately measuring biological information using reflected light from an eardrum. SOLUTION: The biological information measuring apparatus comprises: an infrared light source for emitting infrared light to be irradiated into an earhole; a light guiding part for guiding the infrared light into the earhole; a visual field recognition means for recognizing an area capturing the eardrum of the visual field of the light guiding part; a shutter arranged at a position crossing the optical path of the infrared light, for controlling the area where the infrared light passes through; an infrared light detector for detecting the reflected light of the infrared light reflected inside the earhole; and a biological information operation part for calculating the biological information using the output of the infrared light detector due to the reflected light reflected on the eardrum among the reflected light beams.
