| description | PROBLEM TO BE SOLVED: To provide an antifouling device capable of preventing a structure, a ship or a piping, contacting with seawater from being fouled by the attachment of organisms, constituted of (A) an electroconductive rubber sheet obtained by lining a parts of a body to be prevented from being fouled, comprising an electroconductive or nonconductive material and requiring the antifouling, directly or through a feeding body, (B) an electrode material arranged in the sea so as not to directly contact with the electroconductive sheet, and (C) a direct current source, connected so that the electroconductive rubber sheet may be an anode and the electrode material may be a cathode, and having high electroconductivity in the thickness direction of the rubber sheet to enable a sufficient antifouling electric current to flow. SOLUTION: A rubber sheet obtained by lining a composition obtained by kneading each 15-30 wt.% (total 30-60 wt.%) of an amorphous graphite having 1-20 μm particle diameter and a carbon black having 5-100 μm particle diameter with a butyl rubber, and having |
