Conveyer apparatus for compound sheet

A conveyer apparatus for a compound sheet, comprising:

• a first roll and a second roll that convey a compound sheet obtained by molding a dry electrode compound into a sheet shape, by sandwiching the compound sheet between the first roll and the second roll and rotating,
• wherein a first circumferential surface of the first roll has a first surface roughness,
• wherein a second circumferential surface of the second roll has a second surface roughness greater than the first surface roughness, and
• wherein the second roll is disposed further downstream in a conveying direction of the compound sheet than the first roll, and the compound sheet passing through a gap between the first roll and the second roll is supported and conveyed by the second circumferential surface.
