PROBLEM TO BE SOLVED: To provide a measuring device and electronic apparatus in which SN ratio is improved.SOLUTION: A device comprises: an emission part emitting straight polarized light; a light leading part leading straight polarized light emitted by the emission part with total reflection; a straight polarized light interruption part interrupting the straight polarized light lead by the light leading part; a receiving part receiving light penetrated the straight polarized light interruption part due to contact of living body onto the light leading part, resulting in scattering of the straight polarized light and disorder of polarized light condition; and a measuring part measuring bio-information based on intensity in the light received by the receiving part.SELECTED DRAWING: Figure 10COPYRIGHT: (C)2016,JPO&INPIT【課題】SN比を向上させた測定装置、及び電子機器を提供する。【解決手段】直線偏光を出射する出射部と、前記出射部により出射された前記直線偏光を全反射で導光する導光部と、前記導光部により導光された前記直線偏光を遮断する直線偏光遮断部と、前記導光部に生体が接触されたことにより、前記直線偏光が散乱して偏光状態が乱れ、前記直線偏光遮断部を透過した光を受光する受光部と、前記受光部により受光された光の光量に基づいて、生体情報を測定する測定部とを備えたことを特徴とする。【選択図】図10
