る。2. Description of the Related Art Conventionally, a device for introducing a weak current due to a low frequency or an electric signal such as an electromagnetic wave due to a high frequency from the outside of a living body to a body to promote blood flow and to perform treatment mainly on a massage effect or the like, Bioelectrode pads are used in devices such as electrocardiographs, electroencephalographs, and electromyographs that take out and measure electrical signals from the device. Such a pad requires conductivity, and in recent years, a pad using a hydrous gel base material has been adopted in view of adhesion to a living body surface and skin followability.

は正確な測定ができない場合がある。However, a conventional pad using a gel base material has a relatively thick gel layer formed on both sides of an insulating base material such as a non-woven fabric, and is inferior in terms of adhesion to a living body. A relatively thick gel layer is used. On the other hand, when the thickness of the gel layer on the side fixed to the bioelectrode is increased, the S / N ratio is deteriorated, which may adversely affect the conductivity, and accurate measurement cannot be performed with a measuring device such as a diagnostic instrument. There are cases.

Although the problem is solved, the oozing portion on the back surface is sticky, so that the fixation to the bioelectrode becomes insufficient, or the base material such as a nonwoven fabric alone has no so-called stiffness, so the operability is extremely poor. There are also problems.

The above object is achieved by providing at least one hole of the above, providing a hydrogel on the surface of the insulating substrate on the side of the living body fixed surface, and providing an adhesive layer on the surface of the insulating substrate on the other surface (electrode fixed surface).
