Abstract: The invention provides a packaged tow being characterized in that a carbon fiber precursor tow having a flattened shape in cross section and having a first surface and a second surface opposite to the first surface is layered and packaged in a packaging container in untwisted state. A front end and a back end of the carbon fiber precursor tow thus packaged are placed on a top of the fully-packaged carbon fiber precursor tow. When the front end and a back end of the tow are respectively applied with top/bottom surface identification means to identify top and bottom surfaces thereof, top and bottom surfaces on front ends and back ends of tows packaged in a plurality of packaging containers can be correctly identified and joined. As a result, thread breakage due to heat accumulation in twisted parts in a flame proofing process can be prevented from happening.
