PROBLEM TO BE SOLVED: To provide a biological information detector or the like in which detection accuracy can be improved.SOLUTION: The biological information detector includes a first sensor unit for detecting composite information including biological information of a detection site of a test subject and first noise information originating in external light, and a second sensor unit for detecting second noise information originating in the external light. The first sensor unit has a light-emitting part for emitting first light toward the detection site, a first light-receiving part for receiving light including the biological information obtained from the first light emitted toward the detection site being reflected by the detection site, and the light including the first noise information obtained from the external light being transmitted through the test subject, and a first reflecting part for reflecting the light including the biological information and the light including the first noise information and leading the light to the first light-receiving part. The second sensor unit has a second light-receiving part for receiving the light including the second noise information obtained from the external light being transmitted through the test subject, and a second reflecting part for reflecting the light including the second noise information and leading the light to the second light-receiving part.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、被検査体の被検出部位における生体情報及び外光に起因する第1のノイズ情報を含む合成情報を検出する第1のセンサー部と、外光に起因する第2のノイズ情報を検出する第2のセンサー部と、を含む。第1のセンサー部は、被検出部位に向かう第1の光を発する発光部と、被検出部位に向かう第1の光が被検出部位にて反射された生体情報を有する光、及び外光が被検査体内を透過した第1のノイズ情報を有する光を受ける第1の受光部と、生体情報を有する光及び第1のノイズ情報を有する光を反射させて第1の受光部に導く第1の反射部と、を有する。第2のセンサー部は、外光が被検査体内を透過した第2のノイズ情報を有する光を受ける第2の受光部と、第2のノイズ情報を有する光を反射させて第2の受光部に導く第2の反射部と、を有する。【選択図】 図1
