Even when a low heat-resistant substrate or glass substrate is used, a conductive film composite having both good adhesion of the conductive film to the substrate and excellent conductivity of the conductive film, and The manufacturing method is provided. A substrate, a resin layer formed on at least a part of the substrate, and a conductive film formed on at least a part of the resin layer, and the conductive film is a sintered body of silver fine particles, The main component of the resin layer is a polyurethane resin having a breaking elongation of 600% or more, and the polyurethane resin is -COO-H, -COOR, -COO - NH + R 2 , -COO - NH 4 + (provided that R, R 2 is each independently a linear or branched alkyl group, cycloalkyl group, alkylene group, oxyalkylene group, aryl group, aralkyl group, heterocycle which may have a substituent. A functional group represented by: a group, the same alkoxy group, the same alkoxycarbonyl group, and the same acyl group). |
