PROBLEM TO BE SOLVED: To measure pulse waves by imaging a user, with a simpler configuration.SOLUTION: A pulse wave measurement device 140 includes: a visible light receiving part 102A having a first surface and a pulse wave calculation part 109A. When a vehicle including the visible light receiving part 102A is seen in side view, the first surface is located in a first region between a first light path of first reflection light and a second light path of second reflection light, the eyes of a user seated on a vehicle seat emit first light and the cheeks of the user emit second light, the upper end of a room front mirror of the vehicle reflects the first light and outputs the first reflection light, the upper end reflects the second light and outputs the second reflection light, and the pulse wave calculation part 109A calculates pulse waves of the user on the basis of the waveform of visible light received by the visible light receiving part 102A via the first surface, and outputs the calculated pulse waves.SELECTED DRAWING: Figure 29COPYRIGHT: (C)2018,JPO&INPIT【課題】より簡易な構成によりユーザを撮像して脈波を計測する。【解決手段】脈波計測装置140は、第1表面を有する可視光受光部102Aと、脈波算出部109Aを含み、可視光受光部102Aを含む車両が側面視された場合、第1表面は、第1反射光の第1光路と第2反射光の第2光路との間の第1領域に位置し、車両のシートに着座したユーザの目は第1光を出射し、前記ユーザの頬は第2光を出射し、車両の室内フロントミラーの上端は第1光を反射して第1反射光を出力し、上端は第2光を反射して第2反射光を出力し、脈波算出部109Aは、第1表面を介して可視光受光部102Aが受光した可視光の波形に基づいてユーザの脈波を算出し、算出した脈波を出力する。【選択図】図29
