Abstract
Disclosed is a bioelectric impedance measuring apparatus which can prevent such abnormal condition than an excessive current is applied to a human body when elements in the circuit has failed or is damaged, with a simple circuit configuration and without decreasing the measuring accuracy of the bioelectric impedance. The bioelectric impedance measuring apparatus according to the present invention is configured such that a capacitor or a set of a capacitor and a resistor arranged in parallel with each other is installed between an electrode to be brought into contact with a human body and a bioelectric impedance measuring circuit section comprising a generating section for generating an alternating current applied to a human body for measurement, a measuring section for measuring a voltage value between the portions where the current is applied to the human body, a computing section for computing a bioelectric impedance value, and a central processing unit (CPU).
