To solve problems of a conventional organism measuring instrument wherein measurement results are generally displayed numerically, but recently, the measurement results come to be graphically displayed, displayed by sites for every measurement items, or displayed into a plurality of items by sites, however, when a user tries to display a plurality of measurement items according to the sites of the organism, it is hard to see because there are too many displays of the numerical values or, when the user tries to graphically display them, the operation to select a target graph may be difficult.

This organism measuring instrument is provided with a plurality of electrodes to be brought into contact with respective sites of the organism, a current supply means passing a current to the electrodes, a voltage measuring means measuring the voltage of the electrodes, a changeover means changing over among the plurality of electrodes to which electrode the current is passed and to which electrode voltage is measured, a control means controlling the current supply means, the voltage measuring means and the changeover means, and a display means connected to the control means and displaying the measurement results. The instrument is further provided with a means selecting display items and a means selecting the respective sites of the organism, and displays the measurement results selected by the two selecting means on the display means.
