PROBLEM TO BE SOLVED: To provide a biological information detector improving the accuracy in detection.SOLUTION: The biological information detector includes: a light emitting part 14 a light receiving part 16 for receiving light R1 having biological information which is the light R1 emitted from the light emitting part 14 and reflected on a detected region O of a subject a reflection part 18 for reflecting the light R1 emitted from the light emitting part 14 or the light R1 having the biological information and a substrate 11 having a first surface 11A and a second surface 11B opposed to the first surface with the light receiving part 16 disposed on either the first or second surface and the light emitting part 14 disposed on the other surface. The substrate 11 is composed of a transparent material to the wavelength of the light R1 emitted from the light emitting part 14. At least one of the first and second surfaces of the substrate 11 has a shading region including wiring 61 and a translucent film 11-1 disposed at least in a region excluding the shading region as seen from the top.COPYRIGHT: (C)2011,JPO&INPIT【課題】 検出精度を向上可能な生体情報検出器等を提供する。【解決手段】 生体情報検出器は、発光部14と、発光部14が発する光R1が被検査体の被検出部位Oにて反射された、生体情報を有する光R1’を受ける受光部16と、発光部14が発する光R1又は生体情報を有する光R1’を反射させる反射部18と、第1の面11A及び第1の面と対向する第2の面11Bを有し、第1の面又は第2の面の何れか一方に受光部16がその他方に発光部14が配置される基板11と、を有する。基板11は、発光部14が発する光R1の波長に対して透明な材料で構成され、基板11の第1の面及び第2の面の少なくとも一方は、配線61を含む遮光領域と、平面視において、遮光領域を除く領域に少なくとも配置された光透過膜11-1とを有する。【選択図】 図3
