ABSTRACT:
In an ultrafine metal powder slurry containing an organic solvent, a surfactant, and an ultrafine metal powder, the surfactant is oleoyl sarcosine, the content of the ultrafine metal powder in the ultrafine metal powder slurry is 70 to 95 percent by mass, and more than 0.05 to less than 2.0 parts by mass of the surfactant is contained relative to 100 parts by mass of the ultrafine metal powder. By the above slurry, reduction in labor and treatment time can be realized in a conductive paste forming process. In addition, since aggregation of particles of the ultrafine metal powder is prevented, an ultrafine metal powder slurry can be provided having superior dispersibility and dry film density.
