However, in this type of low-frequency treatment device, the adhesive pad is easily provided along the body by providing a bent portion at the center of the divided body. However, the portion of the affected part to which the adhesive pad is attached has a curved surface. If there is, the adhesive pad itself is stuck on the rigid divided body bottom and does not bend,
The edge of the adhesive pad will float, so
Since the current-carrying area is small, the current value per unit area is large, and the smaller the contact area is, that is, the more the affected part is bent, the more tingling it feels and the treatment becomes. There was a problem in that the sensation deteriorated and the treatment efficiency deteriorated.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned drawbacks, and has as its object to provide a low-frequency treatment device having good flexibility and a large contact area.

[0006]

SUMMARY OF THE INVENTION The present invention provides a flexible sheet, an electrode laminated on the sheet and having a conductive and low-frequency current, and a conductive and adhesive layer laminated on the electrode. The sheet is characterized in that the sheet has a horizontally long shape, and a constricted portion is formed substantially at the center in the longitudinal direction and inside from the outer periphery.

Further, the constricted portion is formed on both sides of the sheet.

Further, the electrode is characterized in that carbon is printed on the sheet.

[0009] The adhesive pad is laminated on a portion excluding a straight line connecting the constricted portions.

[0010] A body for outputting a low frequency current to the electrode,
It is characterized by being provided on a straight line connecting the constricted portions, and fixing the main body and the sheet substantially at the center of the constricted portions.

In the above-described low-frequency treatment device, the sheet is easily bent by the constricted portion of the sheet, and when the sheet is attached to the affected part, the adhesive pad is attached to the entire body by the adhesive force of the adhesive pad. Can be shed.

Further, since the constricted portions are formed on both sides in the longitudinal direction of the sheet, the sheet is easily bent at the central portion of the sheet.

Further, since the electrodes are carbon-printed, the bending of the sheet itself is not impaired.

Since the adhesive pad is provided on the portion excluding the straight line connecting the constricted portions, the adhesive pad is not provided on the straight line connecting the constricted portion, so that the flexibility is better than other portions. And it becomes easier to follow the affected area.

A main body for outputting a low-frequency current to the electrode is provided on a straight line connecting the constricted portion and the main body and the sheet are fixed substantially at the center of the constricted portion, so that the main body does not obstruct the bending of the sheet. The entire adhesive pad can be attached to the affected area.
