PROBLEM TO BE SOLVED: To provide a technology accurately acquiring biological information.SOLUTION: A biological information acquisition device includes a light emitting part for irradiating light onto a living body, a plurality of light receiving parts for receiving the light passing through the living body, and a control part for controlling the light emitting part and the plurality of light receiving parts. The control part acquires a plurality of light receiving results by causing the light emitting part to emit the light as a light emitting part for measurement, and causing the plurality of light receiving parts for measurement separated from the light emitting part for measurement by a first distance out of the plurality of light receiving parts to receive the light irradiated from the light emitting part for measurement, and acquires biological information by using a first light receiving result with the maximum light receiving intensity and a second light receiving result with the minimum light receiving intensity out of the plurality of light receiving results.SELECTED DRAWING: Figure 7【課題】生体情報を精度良く取得する技術を提供する。【解決手段】生体情報取得装置は、生体へ光を照射する発光部と、前記生体を透過した光を受光する複数の受光部と、前記発光部と前記受光部とを制御する制御部と、を備え、前記制御部は、前記発光部を測定用発光部として発光させ、前記測定用発光部から照射された光を、前記複数の受光部のうち、前記測定用発光部から第1の距離だけ離れた複数の測定用受光部に受光させることにより複数の受光結果を取得し、前記複数の受光結果のうち、受光強度が最も大きい第1の受光結果と、受光強度が最も小さい第2の受光結果とを用いて、生体情報を取得する。【選択図】図7
