Abstract
A sheet comprising fibers, resin, and a marking. The resin is a fusion bonding resin, and the fibers are bound to each other by melting the fusion bonding resin. The fibers include defiberated recycled sheet(s). The marking is formed on a surface of the sheet and readable by a reading unit of a supply unit for supplying feedstock to a recycled sheet manufacturing apparatus. When the marking is read by the reading unit, the reading unit is caused to determine that the sheet is made from defibrated recycled sheet.
