た。Among the above-mentioned conventional electrodes for a living body, the one in which the foam tape is adhered and fixed to the skin of a living body via an adhesive is such that when the living body moves, the foam tape rubs the skin and rashes. There was a problem that it was easy. Further, when the electrode is peeled off from the skin, the adhesive may peel off the keratin of the skin. In addition, the adhesive flows out,
There was also a problem that the adhesive strength deteriorated over time.

てしまうという問題があった。[0005] On the other hand, the biomedical electrode based on AMPS has a feature that it can be firmly adhered to the skin by the adhesive force of AMPS, does not flow out, and the adhesive force is maintained. Further, there is an advantage that even if the living body moves while the electrodes are being worn, the AMPS does not break down, and a rasp effect does not occur and no rash occurs. Moreover, the skin does not become horny when the electrodes are removed. However, AMPS has a problem in that since it has low strength, it is partially peeled off from the backing material when the electrode is peeled off, and remains on the skin.

体用電極を提供することを目的とする。The present invention has been made in view of such a point, and provides a living body electrode in which even when AMPS is used, when the electrode is peeled from the skin, a part of the AMPS does not separate and remain on the skin. The purpose is to do.
