PROBLEM TO BE SOLVED: To provide a noncontact-type electrocardiogram measuring apparatus giving little restriction and inconvenience that a subject may feel by eliminating contact of electrodes with a human body surface and further reliably measuring an electrocardiographic signal without the risk of skin irritation and so on.SOLUTION: First and second noncontact electrodes 3a and 3b are disposed so as to form electrostatic capacities C3a and C3b towards a human body 2, and the first noncontact electrode 3a is connected with a charge power supply 7 switchable at a high speed, via a changeover switch 6. The second noncontact electrode 3b is grounded. The first noncontact electrode 3a is charged when it is connected to the charge power supply 7 and discharged when it is unconnected. A voltage measuring part 8 detects a voltage being discharged from the first noncontact electrode 3a to acquire an electrocardiographic signal.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】電極を人体表面に接触しないことから被験者の感じる制約や不便さが小さく、皮膚のかぶれ等の虞がなく、しかも心電信号をより確実に計測する非接触式心電計測装置を提供する。【解決手段】人体2との間に静電容量C3a、C3bを形成するように第1、第2の非接触電極3a、3bを配置し、第1の非接触電極3aに高速で切換えられる切換スイッチ6を介してチャージ電源7を接続する。第2の非接触電極3bは接地する。第1の非接触電極3aがチャージ電源7に接続されたときに充電され、非接続となったときに放電する。第1の非接触電極3aから放電されるときの電圧を電圧計測部8で検出し心電信号を得る。【選択図】図1
