Abstract
Provided is a photosensitive conductive paste that is unlikely to gel, has superior storage stability and adhesion to a substrate, and can be formed into a fine and thick pattern. In a photosensitive conductive paste containing a powdered base metal, an organic binder having acidic groups and a photosensitive organic component, a powdered base metal processed by surface oxidation treatment and a material such as a polyvalent alcohol having at least four hydroxyls, which forms microgels by reaction with metal hydroxides present on the surface of the powdered base metal, is used.
