An objective is to provide a method for judging the authenticity of a product or component. Provided is a method for judging product or component authenticity. The method includes a step of determining the percentage of radioactive carbon-14 based on ASTM 6866 with respect to at least one constituent that a product or component of interest obtained has. Here, at least one constituent that an authentic product or component has and that corresponds to the constituent of the product or component of interest includes a resin comprising a prescribed percentage of radioactive carbon-14.

Method for judging authenticity and pressure-sensitive adhesive sheet

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.
