PROBLEM TO BE SOLVED: To provide a living body measurement device and a living body measurement method, capable of reducing affection of pulsation, during living body measurement.SOLUTION: A living body measurement device 200 comprises: a phase modulation type interferometer 200a; a first stage 218 capable of holding an object 209; an optical window 217a which is an example of a translucent plate; and a second stage 220 for supporting the optical window 217a. The optical window 217a is disposed between the first stage 218 and the interferometer 200a, in a direction of an optical axis of measurement light of the interferometer 200a. The first stage 218 presses an object 209 to the second stage 220 by gas pressure, for performing living body measurement.SELECTED DRAWING: Figure 1 【課題】生体計測時に拍動の影響を低減させる生体計測装置及び生体計測方法を提供する。【解決手段】生体計測装置２００は、位相変調式の干渉計２００ａと、対象物２０９を保持可能な第１ステージ２１８と、透光板の一例である光学窓２１７ａと、光学窓２１７ａを支持する第２ステージ２２０とを有する。光学窓２１７ａは、干渉計２００ａの測定光の光軸の方向で、かつ第１ステージ２１８と干渉計２００ａとの間に配置されている。第１ステージ２１８は、気体の圧力で第２ステージ２２０に対象物２０９を押し当てて、生体計測を行う。【選択図】図１
