PROBLEM TO BE SOLVED: To provide a biological body measurement device capable of highly accurately measuring biological information.SOLUTION: A biological body measurement device 4 comprises a drive section 41, an electric signal acquisition section, a voltage signal generation section and an amplification section 43. The drive section drives one or more light-emitting elements so as to emit light signals in which light intensity periodically varies from one or more light-emitting elements. The electric signal acquisition section acquires an amount of light of reflection light signals obtained by the light signals being reflected in a biological body object or an electric signal corresponding to an amount of light of transmission light signals obtained by the light signals being transmitted through the biological body object. The voltage signal generation section outputs a voltage signal obtained by removing components equal to a predetermined frequency or less included in the electric signal acquired. The amplification section amplifies the voltage signal and outputs an amplification signal.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】生体情報を高精度に計測することが可能な生体計測装置を提供する。【解決手段】生体計測装置4は、駆動部41と、電気信号取得部と、電圧信号生成部と、増幅部43と、を備える。駆動部は、1以上の発光素子から光強度が周期的に変化する光信号を発光させるべく、発光素子を駆動する。電気信号取得部は、光信号が生体物内で反射された反射光信号の光量、または光信号が生体物を透過した透過光信号の光量に応じた電気信号を取得する。電圧信号生成部は、取得した電気信号に含まれる所定周波数以下の成分を除去した電圧信号を出力する。増幅部は、電圧信号を増幅して増幅信号を出力する。【選択図】図1
