A conductive composition for a biological electrode is capable of reducing the impedance between the electrode and the skin. A conductive gel composition for a biological electrode which is capable of electrically and physically connecting a living body to an electrode element and is composed of at least the following components: (1) a radical-polymerizable unsaturated compound; (2) a moisturizer serving as a plasticizer and functioning to supplementing and promoting the physiological humidifying function of the horny layer; (3) a polymerization initiator; and (4) a crosslinking agent. This moisturizer serves also as a plasticizer and, furthermore, elevates the moisture content in the horny layer at the application of this composition. The above-mentioned composition may further contain a plasticizer selected from among polyhydric alcohols, amines and ethers.
A method of reducing impedance between skin and an electrode element, which comprises adding a moisturizer to a gel composition located between said skin and said electrode element, wherein said moisturizer is urea present in an amount of from 10 to 25% weight based on the total weight of the composition, so as to moisturize a horny layer of skin, and wherein said gel composition comprises:
