  In the present embodiment, the first voltage generator 10-1 is electrically connected to the pair of electrodes 12a (12a-1 and 12a-2). The second voltage generator 10-2 is electrically connected to the pair of electrodes 12b (12b-1 and 12b-2).

It may be performed or may be performed alternately. Also, the application of the first frequency voltage between the electrode 12a-1 and the electrode 12a-2 and the application of the second frequency voltage between the electrode 12b-1 and the electrode 12b-2. Only one of them may be performed.

  FIG. 2 is a perspective view showing an example of the first conductor 3-1. FIG. 3 is a bottom view of the conductor shown in FIG. The electrode 12b-1 according to the present embodiment has a substantially cylindrical shape, and is provided at the center of the bottom surface of the first conductor 3-1. The electrode 12a-1 and the electrode 12a-2 according to the present embodiment have the same shape of a substantially semi-ring shape, and the outer edge and the inner edge thereof are substantially circular along the contour of the bottom surface of the first conductor 3-1. Yes. The electrodes 12a-1 and 12a-2 are arranged symmetrically so as to surround the electrode 12b-1. In the present embodiment, since the bottom surface of the first conductor 3-1 is circular, the area through which the pulse current flows is made as wide as possible by arranging the electrodes 12a-1 and 12a-2 as described above. Can do. Further, since the leakage current from the electrode 12b-1 flows to the electrode 12a-1 and the electrode 12a-2 to the same extent, the leakage current from the electrode 12b-1 flows to the electrode 12a-1 and the electrode 12a-2. The influence on the potential difference can be suppressed.

  Moreover, two edges of the electrode 12a-1 along the radial direction of the bottom surface of the first conductor 3-1, and the electrode 12a-2 along the radial direction of the bottom surface of the first conductor 3-1.

Since the current flows, the treatment portion 14 can be electrically stimulated. Moreover, the treatment part 14 can be heated by setting appropriately the frequency of the voltage applied between a pair of electrodes 12b (12b-1 and 12b-2). Thus, according to the treatment device 1 according to the present embodiment, it is possible to apply electrical stimulation to the treatment portion 14 while heating the treatment portion 14.

The electrode 112-1 is provided on the surface of the first conductor 103-1, and the electrode 112-2 is provided on the surface of the second conductor 103-2. Then, the treatment device 101 is used such that the electrode 112-1 and the electrode 112-2 are in contact with the treatment portion 114.

  As shown in FIG. 4, the inventors initially electrically connected the first voltage generator 110-1 to the electrodes 112-1 and 112-2, and connected the second voltage generator 110-2 to the second voltage generator 110-2. It was electrically connected to the electrode 112-1 and the electrode 112-2. However, the inventors have realized that even in this way, a voltage at the first frequency and a voltage at the second frequency cannot be applied to the treatment portion 114.

The inventors electrically connect the pair of electrodes 12a (12a-1 and 12a-2) electrically connected to the first voltage generator 10-1 to the second voltage generator 10-2. Separately from the electrode 12b-1, the first conductor 3-1 is provided. In this way, it is possible to apply voltages having a plurality of different frequencies to the treatment portion 14. For this reason, for example, it is possible to obtain an effect when each of voltages having a plurality of different frequencies is applied to the treatment portion 14 such as heating the treatment portion 14 and applying an electrical stimulus.
