Title:
CONDUCTIVE FILM, MANUFACTURING METHOD THEREFOR, AND TOUCH PANEL
Document Type and Number:
WIPO Patent Application WO/2016/157585
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a conductive film having thin conductive wiring which has superior conductivity characteristics and which is not easily visible, as well as a method for manufacturing the conductive film, and a touch panel. Provided is a conductive film, comprising a support body and thin conductive wiring which is positioned upon the support body and which contains a binder and a metallic part. In a vertical cross-section of the thin conductive wiring, if a contour line along the surface shape of a surface X of the thin conductive wiring which is on the opposite side of the thin conductive wiring from the support body side is moved from the surface X toward the support body side, and if the position at which the contour line reaches the metallic part included in the thin conductive wiring is defined as the upper end position, the average surface area ratio VA of the metallic part in a region up to 100nm from the upper end position toward the support body side is greater than or equal to 1% and less than 50%. If the contour line is moved further toward the support body side than the upper end position, and if the position at which the metallic part is not included in the thin conductive wiring is defined as the lower end position, the average surface area ratio VM1 of the metallic part in a region 50nm toward the support body side and 50nm toward the surface X side from the midway position between the upper end position and the lower end position is 50% or greater.
