FIG. 4 shows an example of a configuration of a conventional bioelectric induction cord. In FIG. 4, the base ends of a plurality of, for example, ten electrode lead wires 2 each having the electrode 1 connected to the distal end are introduced into the branch portion 3. The ten electrode lead wires 2 are bundled into one in the branch part 3 and the connection cords 4 connected to the branch part 3 are connected.

め、皮膚がムレて炎症を起こしやすい欠点もあった。When a biological signal is measured using the bioelectric induction cord configured as described above, the branch 3 is attached and fixed to a predetermined position on the surface of the living body using an adhesive tape or the like. Then, the ten electrodes 1 connected to the distal ends of the electrode lead wires 2 are attached to the measurement sites of the chest and limbs of the living body. At this time, since the living body mounting surface of the conventional branch portion 3 is substantially flat, the branch portion 3 is likely to slip on the body surface, and noise may be generated in the detected biological signal. In addition, since the branch part 3 is in close contact with the skin surface of the living body, there is a disadvantage that the skin is liable to be irritated and inflamed.

た。On the other hand, since the introduction portions of the chest electrode lead wire and the limb electrode lead wire into the branch portion 3 are close to each other, the branch portion 3
The tape for attaching and fixing to the surface of the living body must be adhered to a position off the center where the tape does not interfere with the electrode lead wires 2, and the branch portion 3 cannot be firmly fixed.
