PROBLEM TO BE SOLVED: To provide a sheet type object conveying device applying sure width expanding force to a sheet type object for conveying it with its wrinkle spread without causing any flaw or breakage in it in a sheet type object oonveying process and usable for spreading a wrinkle even in the vacuum such as inside a deposition machine and to provide a sheet type object manufacturing method using this conveying device. SOLUTION: In this sheet type object conveying device constructed of a group of a plurality of rotational rolls arranged in the sheet type object running direction and brought into contact with a sheet type object for running it, each roll is provided with parts having high roll surface traction force to the sheet object on its both end sides within a width range abutting to the sheet type object. When a roll axial width of a low traction force part arranged on the inside of both end sides of a roll positioned on the upstream side is represented by (a) while a roll axial width of a low traction force part arranged on the inside of both sides of a roll positioned on the downstream side is represented by (b), the following relationships are satisfied: (a)<(b), (a)>=0, b>O. |
