Patent ID: 8568603

Claim:
A method of manufacturing a transparent conductive film having a patterned transparent conductive layer on one surface of a flexible transparent base having a transparent film base, the transparent conductive film having a pattern forming part having the transparent conductive layer on the flexible transparent base and a pattern opening part not having the transparent conductive layer on the flexible transparent base, the flexible transparent base having a thickness of 80 μm or less; comprising the steps of: preparing a laminated body in which a transparent conductive layer that is not patterned is formed on a flexible transparent base, removing a part of the transparent conductive layer to form the pattern forming part having the transparent conductive layer on the flexible transparent base and the pattern opening part not having the transparent conductive layer on the flexible transparent base, and heating the laminated body in which the transparent conductive layer is patterned; wherein the absolute value of the difference H 1 -H 2 between the dimensional change rate H 1 of the pattern forming part and the dimensional change rate H 2 of the pattern opening part in the heat treatment step is less than 0.03%.
