Abstract
The transparent conductor of the present invention comprises a conductive layer containing a conductive particle, a binder, a polymerization initiator, and a radical scavenger. In the transparent conductor of the present invention, the conductive layer contains the radical scavenger in addition to the conductive particle. Therefore, even when the conductive particle is pumped upon irradiation with UV rays, so that a radical occurs in the conductive layer, the radical scavenger contained in the conductive layer captures the radical. This restrains the radical from acting on the remaining polymerization initiator and thereby causing a side reaction. As a result, adjacent conductive particles are restrained from fluctuating the distance therebetween.
