Bioelectrical impedance measuring apparatus
First Claim
1. A bioelectrical impedance measuring apparatus comprising:
- an impedance measurement unit for measuring a bioelectrical impedance which comprises electrodes to contact with a living body, and a determination unit for determining the contact condition of a living body with the electrodes by use of a parameter associated with the phase difference of the living body.

Abstract
There is provided an apparatus capable of carrying out an accurate bioelectrical impedance measurement by determining whether contact of a living body with electrodes used at the time of the bioelectrical impedance measurement is normal or not more accurately. The apparatus uses a parameter associated with a phase difference in determining the contact condition of the living body with the electrodes. As the parameter associated with a phase difference, the apparatus uses a value represented by X/R wherein R is a resistance component in a bioelectrical impedance to be measured and X is a reactance component in the bioelectrical impedance and determines that contact of the living body with the electrodes is not normal when the value of X/R is out of a determination range such as a<X/R<b (a and b are real numbers).
