Patent ID: 8278561

Claim:
A conductive pattern-formed film comprising a conductive pattern formed on a film substrate having flexibility, said conductive pattern comprising conductive fine particles and a viscous substance and being patterned by applying on the film substrate in a pattern and pressurizing, under heating, a material constituted by the conductive fine particles dispersed and filled in the viscous substance, said conductive pattern having a lower portion near a lower surface of the conductive pattern, which lower surface contacts the film substrate, and an upper portion near an upper surface of the conductive pattern opposite the lower surface, and having a density of the viscous substance changing in the conductive pattern in a direction perpendicular to a surface of the film substrate wherein the density of the viscous substance is higher in the lower portion than in the upper portion, said conductive pattern having a density of the fine particles changing in the conductive pattern in a direction perpendicular to the surface of the film substrate wherein the density of the fine particles is higher in the upper portion than in the lower portion.
