PROBLEM TO BE SOLVED: To provide a biological information measuring apparatus that can precisely measure multiple pieces of biological information by itself.SOLUTION: A biological information measuring apparatus 10 includes: a light emitting element LD1 and a light emitting element LD2 that emit light having mutually different wavelengths； a light receiving element 3 that receives light emitted from the light emitting element LD1 and the light emitting element LD2 and outputs light reception signals corresponding to the respective amounts of received light； a signal separating circuit 22 that separates the light reception signals into a first light reception signal corresponding to the amount of light received from the light emitting element LD1 and a second light reception signal corresponding to the amount of light received from the light emitting element LD2； an LPF 24 that removes noise components from the light reception signals； and a measurement unit 20 that measures multiple pieces of biological information based on the first light reception signal before removal of noise components by the LPF 24 and on the first and second light reception signals after removal of noise components by the LPF 24.SELECTED DRAWING: Figure 8COPYRIGHT: (C)2018,JPO&INPIT【課題】１台の装置で複数の生体情報を精度よく測定することのできる生体情報測定装置を提供する。【解決手段】生体情報測定装置１０は、互いに波長の異なる光を照射する発光素子ＬＤ１及び発光素子ＬＤ２と、発光素子ＬＤ１及び発光素子ＬＤ２から照射される各々の光を受光し、受光量に対応した受光信号を出力する受光素子３と、受光信号を、発光素子ＬＤ１から照射される光の受光量に対応した第１の受光信号と、発光素子ＬＤ２から照射される光の受光量に対応した第２の受光信号と、に分離する信号分離回路２２と、受光信号のノイズ成分を除去するＬＰＦ２４と、ＬＰＦによってノイズ成分が除去される前の第１の受光信号と、ＬＰＦ２４によってノイズ成分が各々除去された第１の受光信号及び第２の受光信号と、を用いて複数の生体情報を測定する測定部２０と、を備える。【選択図】図８
