TRANSPARENT FLEXIBLE PRINTED WIRING BOARD AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a transparent flexible printed wiring board superior in adherence of a transparent film and a transparent electroconductive film, flexibility and heat resistance.

SOLUTION: A method for manufacturing the transparent flexible printed wiring board includes: preparing a transparent polyimide film 1 in which a dimensional change rate accompanied by a baking step is ±0.2% or less; printing ITO particulates and ITO ink containing a binder in a predetermined pattern shape on the transparent polyimide film 1 by an inkjet method; subsequently baking the ITO ink at 230°C-300°C; and thereby forming a transparent electroconductive film 2 having a ratio of the binder of 5-10 wt.%.
