Thus, the current density supplied to the entire hydrogel sheet 100 can be made uniform, and the output current from the low-frequency treatment device can be efficiently distributed to the entire hydrogel sheet 100.
- the hydrogel sheet 100 is peeled off from the affected part, and then the connector 102 is pulled out while pressing the site of the fixing member 4. Since the fixing member 4 has rigidity as described above, the electrode conductor 1 can be used repeatedly without damaging the conductive member 3 by such a procedure. Moreover, in this electrode conductor 1, since the connection terminal 2 is formed of a metal having excellent corrosion resistance (stainless steel in this example), the connection terminal 2 can be used even when it is attached to a hydrous gel sheet and used (or left) for a long time. Corrosion is minimized.

That is, in the electrode conductor 1 ′ of the present embodiment, the tip portions of the support portions 37, 37 have a shape extending in all directions within a range not exceeding the outer shape of the hydrogel sheet 100.
- the same effects as those of the first embodiment described above can be obtained. That is, when the electrode conductor 1 ′ is attached to the hydrogel sheet 100, the support 37 supports the hydrogel sheet 100, and the hydrogel sheet such as a non-woven fabric can be stretched. It is possible to prevent sticking of the adhesive surfaces. In addition, since a pair of electrodes (carbon electrodes) are formed on both sides of the connection terminal 2, when attached to the hydrogel sheet 100, it is difficult to peel off against an external force, and the current distribution during energization (and thus to the human body) (Electric feeling) is improved.
