A body fat measurement apparatus is disclosed. The apparatus includes a current-applying electrode pair including two electrodes for applying a current, and a voltage-measuring electrode pair including two electrodes for measuring a voltage. The current-applying electrode pair is provided in such a way that a line which joins the two current-applying electrodes is inclined with respect to a trunk axis of a body to be measured. The voltage-measuring electrode pair is provided between the two current-applying electrodes.
