Abstract

With a conventional cylindrical can method, a region used as a film formation ground electrode is a portion of the cylindrical can, and an apparatus becomes larger in size in proportion to the surface area of the electrode. A conveyor device and a film formation apparatus having the conveyor device are provided, which have a unit for continuously conveying a flexible substrate from one end to the other end, and which are characterized in that a plurality of cylindrical rollers are provided between the one end and the other end along an arc with a radius R, the cylindrical rollers being arranged such that their center axes run parallel to each other, and that a mechanism for conveying the flexible substrate while the substrate is in contact with each of the plurality of cylindrical rollers is provided.
