An electrical treatment device (200) includes a remaining power detection unit (302) that detects a remaining battery power of the electrical treatment device (200)； a treatment content setting unit (306) that sets a treatment content； an impedance measurement unit (304) that measures a bioelectrical impedance of a site on a body of a user by using electrodes that come into contact with the site； a treatment execution unit (312) that performs treatment of the site by controlling a voltage waveform applied to the electrodes； and a determination unit (310) that determines whether treatment in accordance with the treatment content can be executed up until a treatment time elapses on the basis of a current remaining battery power and a power consumption calculated from the bioelectrical impedance and the voltage waveform. When treatment in accordance with the treatment content cannot be executed up until the treatment time elapses, the treatment execution unit (312) modifies a voltage waveform corresponding to the treatment content currently set so that treatment can be executed up until the treatment time elapses, and outputs the modified voltage waveform.
