A beauty apparatus (1) has a first electrode (11) and a second electrode (12) positioned apart from each other, and a control unit (3) configured so as to enable a voltage to be applied between the electrodes. The control unit (3) is configured so as to control a main operation according to a state of contact between the electrodes and a human body. The beauty apparatus (1) has: a means for applying a pulse voltage between the electrodes, and measuring electrical characteristic values inside the control unit (3); a means for determining whether the electrodes are conducting electricity via the human body on the basis of the electrical characteristic values; and a means for starting the main operation when it is determined that the electrodes are conducting electricity.
