TRANSPARENT ELECTRICALLY CONDUCTIVE FILM, TRANSPARENT ELECTRICALLY CONDUCTIVE SHEET AND TOUCH PANEL

摘要

PROBLEM TO BE SOLVED: To provide a transparent electrically conductive thin film or a transparent electrically conductive sheet, and a touch panel using this excels in a pen scribing durability a the time of using for the touch panel, especially, which are not destroyed after 100,000-time scribing examinations by a load of 5.0 N using a pen made from a polyacetal. SOLUTION: The transparent electrically conductive thin film is laminated with a curative substance using hardened type resin as a main composition ingredient, and the transparent electrically conductive thin, at this order, on a transparent plastic film base material. The average roughness (SRa) of the 3-dimensional central surface of the transparent conductive thin film face within a radius of 250μm is 1 to 5 nm.
