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 ).
