Disclosed is a body composition measurement device (1) provided with a current electrode pair (30) for applying current and a plurality of voltage electrode pairs (40A - 40E) for measuring voltage at a plurality of measurement points. A controller (50) measures body fat on the basis of voltages measured at the plurality of measurement points by means of the voltage electrode pairs (40A - 40E). The controller (50) uses the measured voltages at the plurality of measurement points to perform integration and calculates the amount of body fat on the basis of the integration result.
