Electrical treatment device

An electrical treatment device comprising:

• a plurality of electrodes to be in contact with a part of a body of a user;
• and
• a controller that performs a treatment onto the part by applying, to the plurality of electrodes, a first burst wave, a second burst wave, and a third burst wave, wherein
• the controller outputs the first burst wave constituted of a continuous wave of a plurality of pulses each having a first amplitude,
• after outputting the first burst wave, the controller repeatedly outputs the second burst wave constituted of a continuous wave of a plurality of positive pulses each having a second amplitude and the third burst wave constituted of a continuous wave of a plurality of negative pulses each having a third amplitude, and
• the first amplitude is larger than each of the second amplitude and the third amplitude,
• a repetition frequency of each pulse included in the first burst wave is 100 KHz or less,
• a length of the first burst wave is between 20 ms and 60 ms, and
• a repetition frequency of each positive pulse included in the second burst wave is equal to a repetition frequency of each negative pulse included in the third burst wave.
