Abstract
A laminate according to an embodiment of the present invention includes: a resin substrate; a polyvinyl alcohol-based resin layer formed on one side of the resin substrate; and an antistatic layer formed on another side of the resin substrate and comprising a binder resin and a conductive material. The binder resin includes a polyurethane-based resin; the antistatic layer has an arithmetic average surface roughness Ra of 10 nm or more; and the conductive material includes a conductive polymer.
