TRANSPARENT CONDUCTIVE SUBSTRATE PRODUCTION METHOD, TRANSPARENT CONDUCTIVE SUBSTRATE, AND ELECTROSTATIC CAPACITANCE TOUCH PANEL

摘要

Provided are a transparent conductive substrate production method for an electrostatic capacitance touch panel having a high pattern recognition property, by simple steps without using a vacuum process and a wet etching method, as well as a transparent conductive substrate and an electrostatic capacitance touch panel. An electrode drawing lead wiring pattern is formed on at least one main face of a transparent film using a conductive paste. An electrode pattern forming unit prints an electrode pattern with a transparent conductive pattern forming ink containing metal nanowires or metal nanoparticles so that the electrode pattern is connected to the electrode drawing lead wiring pattern, and dries the printed electrode pattern. The dried electrode pattern is subjected to pulsed light irradiation by a photoirradiation unit 18, to sinter the metal nanowires or the metal nanoparticles contained in the transparent conductive pattern forming ink.
