PROBLEM TO BE SOLVED: To provide a package of a polyacrylonitrile fiber bundle, which prevents fibers of the polyacrylonitrile fiber bundle from being entangled or becoming loose and is capable of being transferred while retaining sheet formability of the fiber bundle when manufactured, and from the fiber bundle of which, high-quality polyacrylonitrile oxidized fibers can be manufactured while preventing trouble from occurring when oxidizing treatment such as the burning and the cutting of the fibers is performed. SOLUTION: The package of a polyacrylonitrile fiber bundle employs a packing container in which a bag having moisture barrier properties is provided. The bundles of the polyacrylonitrile fibers whose moisture regain is 10-45% by mass and whose fiber bundle packing density (dry fiber bundle mass basis) is 0.15-0.45 g/cm<SP>3</SP>are folded back and stacked on one another to be airtightly stored in the bag.
