Abstract: A beauty instrument includes a plurality of electrodes separated into a first electrode group and a second electrode group that are continuous with each other. The electrode groups are controlled so that a current supply state and a current supply suspension state are alternated between the two groups every predetermined period of time. An operation of four electrodes of each of the first electrode group and the second electrode group can be so controlled that a positive electric charge of one pair of the electrodes and a negative electric charge of the other pair of the electrodes are alternately replaced with each other with a diagonal line connecting the diagonally disposed two positive electrodes to each other crossing with a diagonal line connecting the diagonally disposed two negative electrodes to each other.
