PROBLEM TO BE SOLVED: To provide a biological information measurement device that can prevent light that should not be received from reaching a receiver to inhibit a decline in signal-to-noise ratio.SOLUTION: The biological information measurement device includes: a sensor with a first receiver capable of receiving light from an organism and a partition material 4 for blocking light from passing that is installed so as to project in an opposite direction to an entrance direction of light from an organism from a part different from the first receiver of the sensor.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】受光すべきでない光が受光部に到達することを防ぎ、信号雑音比の低下を抑えることのできる生体情報測定装置を提供する。【解決手段】生体情報測定装置は、生体からの光を受光可能な第1受光部を有するセンサと、センサの第1受光部と異なる箇所から、生体からの光の進入方向と反対の方向に突出するように設けられた、光の通過を遮る仕切材4と、を備える。【選択図】図1
