(57) [Summary] [Purpose] There is little deterioration of conductivity, excellent storage stability, Provide safe aqueous conductive paint. [Structure] A water-based polyurethane resin containing an organic polyisocyanate compound and a polyol compound having a carboxyl group as essential components has a specific surface area of 2000 by the BET method. In cm 2 / g ~10000cm 2 / g , and passed through a sieve of 44 .mu.m 90% by weight or more, the amount of oxygen is mixed and dispersed crushing copper powder electrolytic copper powder or electrolytic copper powder is less than 0.2 wt% Waterborne conductive paint |
