To accurately analyze a pulse wave.SOLUTION: A pulse wave analysis device includes: a first light emitting element for irradiating a living body with a light whose peak wave length is 525-560 nm； a second light emitting element for irradiating the living body with a light whose peak wave length is 490-580 nm, which is different from the peak wave length of the light emitted by the first light emitting element； a light reception unit for generating a first detection signal corresponding to reception intensity of the light which is emitted from the first light emitting element and passes inside the living body, and a second detection signal corresponding to reception intensity of the light which is emitted from the second light emitting element and passes inside the living body； and a calculation unit for calculating a pulse index on a pulse wave of the living body from the first detection signal and the second detection signal.SELECTED DRAWING: Figure 2【課題】高精度に脈波を解析する。【解決手段】ピーク波長が５２５ｎｍ以上５６０ｎｍ以下である光を生体に照射する第１発光素子と、ピーク波長が、前記第１発光素子が出射する光のピーク波長とは異なり、４９０ｎｍ以上５８０ｎｍ以下である光を前記生体に照射する第２発光素子と、前記第１発光素子から出射して前記生体の内部を通過した光の受光強度に応じた第１検出信号と、前記第２発光素子から出射して前記生体の内部を通過した光の受光強度に応じた第２検出信号とを生成する受光部と、前記第１検出信号および前記第２検出信号から前記生体の脈波に関する脈指標を算出する算出部とを具備する脈波解析装置。【選択図】図２
