A clip for a sheet electrode, which is capable of easily and reliably pinching a sheet electrode, and capable of minimizing the number of parts, thus facilitating the assembling. This clip is constructed such that a movable plate ( ) provided with slots ( ) to be engaged with supporting axes ( ) is engaged with a substrate ( ) having the supporting axes ( ), and a conductive leaf spring ( ) which is bent in the near middle thereof is interposed between the substrate and movable plate so as to keep them in an opened state. After the insertion of a sheet electrode ( ), the movable plate is pivoted against the force of the leaf spring so as to close and pinch the sheet electrode. When the movable plate is further shifted forward along the slots, the movable plate is fixingly engaged with the substrate, thereby maintaining the pinching of the sheet electrode.

An electrically conductive polymer gel is composed of a crosslinked polyacrylamide polymer including an electrolytic salt, water and a polyhydric alcohol uniformly dissolved therein, wherein the water and the polyhydric alcohol are major components of said polymer gel. The polyacrylamide series polymer in the gel has properties of being hydrophilic and being a nonelectrolyte. Therefore, a desirable connection between the gel and the electrode can be achieved with low impedance. Moreover, the polyhydric alcohol reduces the drying speed of the electrically conductive polymer gel, thereby preventing an increase in the impedance due to the dryout of the gel. Therefore, the electrically conductive polymer gel of the present invention permits an accurate measurement of an electrical phenomenon in an organism for long periods of time.

Expandable phenolic resin-coated composite beads comprise an aggregate having coated thereon a solid, expandable resin composition comprising a solid, phenolic resin initial condensation product, a foaming agent and, if necessary, a hardening agent. The expandable phenolic resin-coated composite beads provide composite cellular moldings in which the aggregates are uniformly dispersed in a phenolic resin-expanded layer and are firmly adhered to the expanded layer. The composite cellular moldings can be adhered to a face plate to form integral laminates.
