Abstract
The present invention provides a sheet-shaped material containing an RFID thread. The RFID thread comprises a strip-shaped film onto one side of which a semiconductor chip containing plural bits of memory and provided with an antenna wire is bonded. The strip-shaped film has plural openings formed therethrough except where the semiconductor chip is bonded. Since intertwining occurs between paper fibers via the openings, the RFID thread is strongly fixed in the paper.
