Abstract:
To provide a conductive pattern formation method capable of improving conductivity of a conductive pattern and a composition for forming a conductive pattern by means of photo irradiation or microwave heating. A composition for forming a conductive pattern that contains copper particles each having a copper oxide thin film formed on the entire or a part of a surface thereof, plate-like silver particles each being 10 to 200 nm thickness, and a binder resin is prepared. The composition for forming a conductive pattern is printed in a pattern having a desired shape on a substrate. Photo irradiation or microwave heating is applied to the printed pattern to thereby produce a copper/silver sintered body, to form a conductive film.
