For laser processing a conductive paste

Disclosed has a viscosity suitable for printing, the surface to form fine signal lines such that it can be formed smooth coating easily, with having good laser processability, adhesion to a substrate, heat and an object thereof is to provide a laser processing for the conductive paste to hold the moisture resistance environmental reliability. A and the binder resin, the conductive fine particles include inorganic flake particles, and a dispersant, wherein the aspect ratio of the inorganic flake particles is 4 to 40, for laser processing a conductive paste. The average particle diameter of the inorganic flake particles is preferably 1 to 5 [mu] m. .FIELD 1
