Abstract:
1. A transparent flexible printed wiring board, comprising: a transparent insulating film whose dimension change rate in association with a heat process at 230 to 300° C. is not larger than ±0.2%; a transparent conductive film obtained by baking ITO ink and formed on the transparent insulating film, the transparent conductive film having a binder ratio of 5 to 10 wt %; a heat-resisting transparent first insulating protection film which is formed so as to coat the transparent conductive film and has an opening, a part of the transparent conductive film being exposed on the bottom surface of the opening; a jumper joint section formed by drying PEDOT ink printed inside the opening and on the first insulating protection film; and a heat-resisting transparent second insulating protection film formed so as to coat the jumper joint section.
