Body fat measuring apparatus

The present invention relates to a body fat measurement apparatus comprising an impedance measurement electrode system comprising a pair of current supply electrodes and a pair of voltage measuring electrodes, which are adapted to be in contact with the outer surface of the waist of the person under test in order to measure abdominal impedance, body fat index is calculated based on the measured abdominal impedance staff. According to the invention, the apparatus further comprising: an electrode support means; lateral width measuring unit; and an arithmetic unit, wherein the front surface of the electrodes abdominal support unit supports an impedance measuring electrode system, so that the system under test persons contact, thereby abdominal impedance measurement, the lateral width of the lateral width of the abdomen measuring unit measured person is measured, and the arithmetic unit calculates the body fat index according to the measured abdominal impedance, and personnel lateral width.
