PROBLEM TO BE SOLVED: To provide a technique to improve the measurement accuracy of a device which measures a pulse wave using a plurality of light sources.SOLUTION: A pulse wave measuring device comprises: a first light emitting unit which irradiates a pulse wave measurement site with light of a first wavelength a first light receiving unit which receives the light of the first wavelength reflected off the measurement site and outputs a measurement signal based on an amount of received light a second light emitting unit which irradiates the measurement site with light of a second wavelength a second light receiving unit which receives the light of the second wavelength reflected off the measurement site and outputs a measurement signal based on an amount of received light, and which is arranged in a position where a line segment connecting the first light emitting unit and the first light receiving unit intersects a line segment connecting the second light emitting unit and the second light receiving unit when viewed from the measurement site and a generation unit which generates a pulse wave signal indicative of the pulse wave on the basis of at least one of the first measurement signal output by the first light receiving unit and the second measurement signal output by the second light receiving unit.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】複数の光源を用いて脈波の測定を行う装置において、測定の精度を高くすることのできる技術を提供する。【解決手段】脈波測定装置は、脈波を測定する測定部位に第1の波長の光を照射する第1の発光部と、前記第1の波長の光が測定部位で反射した光を受光し、受光量に基づく測定信号を出力する第1の受光部と、前記測定部位に第2の波長の光を照射する第2の発光部と、前記第2の波長の光が測定部位で反射した光を受光し、受光量に基づく測定信号を出力する第2の受光部であって、前記測定部位からみた場合に前記第1の発光部と前記第1の受光部とを結ぶ線分と、前記第2の発光部と前記第2の受光部とを結ぶ線分とが交差する位置に設けられた第2の受光部と、前記第1の受光部が出力する第1の測定信号及び前記第2の受光部が出力する第2の測定信号の少なくともいずれか一方に基づいて脈波を示す脈波信号を生成する生成部とを備える。【選択図】図1
