In a state where the small EMS main body 3 is attached to the electrode pad 1, the electrode pad 1 is attached to a place to be applied and used.

  Next, how the electrode pad 1 according to the present invention is used will be described with reference to FIGS. 5 and 6 are perspective views showing a state in which the electrode pad is applied to the face.

  When the electrode pad 1 according to the present invention is used, first, the hook terminals 30 and 31 of the EMS main body 3 are engaged with the pins 15a and 16a of the power supply terminals 15 and 16 of the electrode pad 1, and the EMS main body 3 and The electrode pad 1 is electrically connected.

  The first electrode portion 11 of the electrode pad 1 is formed in an arcuate shape, and as shown in FIG. 5, the first electrode portion 11 is attached along the present direction. When the electrode pad 1 is attached in this manner and the EMS body 3 is turned on, when a weak current is passed through the skin through the electrode pad 1, the muscle is stimulated by the current and starts contracting. By attaching the electrode pad 1 as shown in FIG. 5, the ocular muscles and zygomatic muscles can be stimulated.

  By stimulating the ocular muscles, the generation of wrinkles in the eyes is suppressed and the wrinkles are reduced. In addition, by stimulating the zygomatic muscles, sagging of the cheeks is taken and wrinkle generation is suppressed.

  As shown in FIG. 6, the electrode pad 1 may be affixed with the first electrode portion 11 along a conical line at the mouth. By attaching the electrode pad 1 in this way, it is possible to stimulate the muzzle muscles and the zygomatic muscles. By stimulating the muzzle muscles, the generation of wrinkles at the mouth is suppressed and the wrinkles are reduced. In addition, by stimulating the zygomatic muscles along with the muzzle muscles, sagging of the cheeks is taken, and the deepening of the constriction line is suppressed.

  The electrode pad 1 configured as described above has the following effects.

  According to the electrode pad of the present invention, both electrode portions are arranged with the constricted portion of the insulating sheet interposed therebetween, and a slit is formed in each of the constricted portion and both electrode portions, so that the skin is formed by the constricted portion and the slit. Can be sufficiently absorbed, and even if an electrode pad is attached to the undulating skin surface, it does not float and adheres well and is difficult to peel off.

  In addition, even if the skin moves finely during the operation of the EMS, the electrode pad does not float by sufficiently absorbing the fine movement of the skin by the slit and the constricted portion, and it is difficult to peel off because sufficient adhesion can be maintained. .

  Further, since the two electrodes are formed on one insulating sheet, it is easier to handle than two electrodes and the insulating state can be reliably maintained.

  In addition, the first electrode portion is formed in a strip shape, and both end portions are protruded outward and curved in an arc shape, thereby providing an electrode pad that can be particularly suitably used for the eyes and mouth. And since it has sufficient adhesiveness by a slit and a constriction part, there is much sebum like a face, and even if it sticks to the part where skin is easy to move, it does not peel off.

  As in the above-described embodiment, even when a small EMS body is directly attached to the electrode pad, the electrode pad is sufficiently adhered to the skin and firmly attached and does not peel off. Since it is possible to use it by directly attaching to the EMS, there is no need for a lead wire for electrically connecting the EMS main body and the electrode pad. Doing other tasks such as housework and exercise while doing massages, etc. will not get in the way.
