Abstract
This sheet manufacturing apparatus is provided with: a nozzle for extruding a heated resin sheet; a main roll with a surface on which microstructures are formed; a follower roll disposed at a distance from the main roll; and an electricity-supplying mechanism. The electricity-supplying mechanism heats an electrically conductive section of the main roll by supplying electricity to the electrically conductive section from both edges of the main roll.
