At a tape reel having a hub on which a recording tape T is wound and flanges which are provided at both end portions of the hub, a large diameter portion, whose diameter is larger than diameters of both end portion sides of the hub, is formed at the hub. The large diameter portion is offset, from a widthwise direction central portion of the hub, toward the one flange side or the other flange side.
