PURPOSE: To permit convenient use by mounting a slave main body on a master main body in freelly attachably and detachably and providing the master main body or the slave main body with a housing part for housing a cord which connects the output end of a low-frequency output circuit part to a second conductive piece.
CONSTITUTION: A pair of first conductive pieces 5 and 5' of a master main body 2 abut on the skin of a human body under the condition where a slave main body 2 is mounted on a master main body 1, and power is supplied from a power supply part 4 to a low-frequency output circuit part 3. Then, a low-frequency current flows through the human body to a part between the first conductive pieces 5 and 5', and low-frequency treatment is carried out. Under the conditions where the slave main body 2 is separated from the master main body 1, the first conductive pieces 5 and 5' of the master main body 1 and a second conductive piece 8 of the slave main body abut on the skin of the human body, and the low-frequency current flows between the first conductive pieces 5 and 5' and the second conductive piece 8 for low-frequency treatment. In addition, when the slave main body 2 is mounted on the master main body 1 during use, a cord 22 can be housed in a housing part 24 so that a cord 12 will not be a hindrance. Thus, convenient use is permitted.
