Abstract

A body composition measuring device and method which can perform measurement of the value about body composition also to those who have a deficit in the limbs are provided. A plurality of current applicators and voltage measurement electrodes are provided. A body composition measuring device measures body composition by bioelectricity impedance measurement, and body composition is measured from a value of bioelectricity impedance measurement using a plurality of regressions. A plurality of electrodes for current application and voltage measurement electrodes are made to correspond to the left hand, right hand, left foot, and right foot for a person being measured. In addition, a plurality of regressions is made to correspond to a value of bioelectricity impedance measurement of an electrode corresponding to between both feet, between both hands, right half body, left half body, right hand, left hand, right foot, left foot, and trunk.
