An object of the present invention is to provide a fiber package in which a partially split carbon fiber bundle is wound around a bobbin, and which has no problem in unwindability. A fiber package is provided, which is a square-end type fiber package formed by traverse winding a fiber bundle (12) around a bobbin, in which the fiber bundle (12) is partially split into sub-bundles (11), and the width W of the fiber bundle (12) is smaller than the total sum of the widths Ws of the sub-bundles (12). A fiber package is also provided, which is a square end type fiber package formed by traverse winding a fiber bundle (12) around a bobbin, in which the fiber bundle (12) is partially split into sub-bundles (11) and is wound around the bobbin so as to cause the sub-bundles (11) to overlap each other.
