ABSTRACT:
A reel around which a fine metal linear material, such as a filament for a tire cord, a saw wire, or the like, is wound, is formed by fixedly joining flanges (2) made of a steel sheet and having a hollow ring-shaped outer edge reinforcing portion (8) at an outer edge to both ends of a winding drum (1). In the outer edge reinforcing portion (8) of the flange (2), an outer edge portion of the flange (2) is bent back outward in a reel axial direction at a substantially right angle with respect to a substantially flat inner surface thereof and is then curled inward in a radial direction so that the metal linear material can be wound up to the very outer edge of the flange (2).
