Abstract
A small biological information acquisition device that can noninvasively acquire biological information is provided. The biological information acquisition device includes a first light emitting elementA serving as a first infrared light source that is used for acquiring positional information of blood vessels and emits infrared light having a peak wavelength λ1, and a second light emitting elementB serving as a second infrared light source that is used for spectral analysis and emits infrared light having a peak wavelength λ2 different from the peak wavelength λ1.
