First Claim
1. A body fat measuring device comprising:
- at least one pair of first electrodes configured to be disposed respectively at a first site and a second site, wherein the first site and the second site are located away from an abdomen of a subject, and said abdomen is located between the first site and the second site;
an electrode group including a first abdomen electrode configured to be disposed at a surface of the abdomen of said subject,said first abdomen electrode including a pair of second electrodes and a pair of third electrodes disposed in an alignment direction substantially perpendicular to a cross section of said abdomen;
an applying portion for alternately applying electric current to said subject via said first electrodes and said third electrodes;
a detecting portion for alternately detecting a first potential difference between the pair of second electrodes when the electric current is applied via said first electrodes, and a second potential difference between the pair of second electrodes when the electric current is applied via said third electrodes; and
a visceral fat amount calculating portion for calculating a visceral fat amount of said subject based on said detected first and second potential differences and physical data of said subject.

Abstract
A body fat measuring device includes at least one pair of first electrodes to be disposed respectively at a first site and a second site sandwiching the abdomen of a subject, and an electrode group including a first abdomen electrode to be disposed at a surface of the abdomen of the subject. The first abdomen electrode includes a pair of second electrodes and a pair of third electrodes disposed in an alignment direction substantially perpendicular to a cross section of the abdomen. In a case where electric current is applied via the first electrodes, a first potential difference between electrodes of one predetermined pair included in the first abdomen electrode is detected. In a case where electric current is applied via the third electrodes, a second potential difference between the second electrodes is detected. Based on the detected two types of potential differences and physical data of the subject, the visceral fat amount of the subject is calculated.
