Summary:To provide a reflective photoelectric volume pulse wave sensor which is capable of combining wearing feeling with measurement accuracy by facilitating positioning between a blood vessel and a light-receiving element and improving robustness of a measurement position.SOLUTION: A reflective photoelectric volume pulse wave sensor 100 is provided with a planar light emitting element 500 and a light-receiving element 400. In a plane view, a maximum longitudinal length L1 of a light-receiving part 40 of the light-receiving element 400 is within a 5-100 mm range.SELECTED DRAWING: Figure 16 【課題】本発明の課題は、血管と受光素子との位置合わせが容易で、測定位置のロバスト性を向上させることができ、装着感と測定精度の両立を図ることができる反射型光電容積脈波センサーを提供することである。【解決手段】本発明の反射型光電容積脈波センサー１００は、面状の発光素子５００と、受光素子４００を備えた反射型光電容積脈波センサー１００であって、平面視において、前記受光素子４００の受光部４０の長軸方向の最大の長さＬ１が、５～１００ｍｍの範囲内であることを特徴とする。【選択図】図１６
