Disclosed is an apparatus (10) for measuring body fat which comprises: a current applying electrode pair (31) including two electrodes (31A 31B) for applying a current and a voltage measuring electrode pair (41) including two electrodes (41A 41B) for measuring a voltage. The current applying electrode pair (31) is provided in such a way that a line which joins the two electrodes (31A 31B) for applying a current is inclined with respect to a trunk axis (CB) of a body (70) to be measured. The voltage measuring electrode pair (41) is provided between the two electrodes (31A 31B) for applying a current.
