PROBLEM TO BE SOLVED: To provide a biological component measuring device which non-invasively performs high accuracy biological component measuring, and to provide a biological component measuring method.SOLUTION: The biological component measuring device 10 includes: a guide plate 11 where a part of a living body 20 is placed a light source 18 for generating light to pass through the living body placed on the guide plate 11 in the width direction of the guide plate 11 a light reception part 19 for receiving the light coming through the living body 20 optical path change parts 15a, 15b, 16a, 16b for changing an optical path between the light source 18 and the light reception part 19 and a control part 17. The control part 17 determines the optimum optical path, on the basis of an OCT image or the intensity of scattered light, etc., controls the optical path change parts 15a, 15b, 16a, 16b to allow the light emitted from the light source 18 to pass through the optimum optical path, and measures a biological component, on the basis of a signal to be output from the light reception part 19.COPYRIGHT: (C)2013,JPO&INPIT【課題】非侵襲で精度良く生体成分を測定できる生体成分測定装置及び生体成分測定方法を提供する。【解決手段】生体成分測定装置10は、生体20の一部を載置するガイド板11と、ガイド板11の上に載置された生体内をガイド板11の幅方向に透過する光を発生する光源18と、生体20内を透過した光を受光する受光部19と、光源18と受光部19との間の光路を変更する光路変更部15a,15b,16a,16bと、制御部17とを有する。制御部17は、OCT像又は散乱光の強度等に基づいて最適光路を決定し、光源18から出射された光が最適光路を通るように光路変更部15a,15b,16a,16bを制御して、受光部19から出力される信号に基づいて生体成分を測定する。【選択図】図1
