Abstract
The present invention is a transparent conductive film having a flexible transparent base and a transparent conductive layer made of a crystalline conductive metal oxide that is formed on one surface of the flexible transparent base, in which the thickness of the flexible transparent base is 80 μm or less, and the difference H1−H2 between the dimensional change rate H1 when the transparent conductive film is heated at 140° C. for 30 minutes and the dimensional change rate H2 when the transparent conductive layer is removed from the transparent conductive film by etching and the transparent conductive film is heated at 140° C. for 30 minutes is −0.02 to 0.043%. Because of that, the level difference at the pattern boundary when the film is assembled into a touch panel, etc. is decreased and the deterioration of the appearance can be also suppressed.
