Abstract
Provided is a capacitive touch panel which has enhanced sensitivity and is usable in an image display panel, etc. in this capacitive touch panel, a window, a first transparent film having a first transparent conductive electrode pattern formed on one surface thereof, and a second transparent film having a second transparent conductive electrode pattern which is formed on one surface thereof and disposed with respect to the first transparent film in such a manner as to allow a capacitance to be formed therebetween, are stacked in turn. The capacitive touch panel comprises a first transparent inter-layer resin provided between the window and the first transparent film, and a second transparent inter-layer resin provided between the first transparent film and the second transparent film, wherein the first transparent inter-layer resin has a dielectric constant greater than that of the second transparent inter-layer resin.
