To provide a physical distribution reel suitable for securing rigidity while economizing a resin quantity required for molding in forming a wide flat surface suitable for sticking printed matter, on a flange.

The injection-molded physical distribution reel 1 with a label 4 and other printed matter stuck to a partial area of a flange outer surface comprises a core 2 wound with a long-sized material, and a pair of disk-like flanges 3, 3 provided at both ends of the core 2. The outer surface of the printed matter sticking area is formed to be flat, while the inner surface of the printed matter sticking area is formed with a thinned wall part 38 reducing the wall thickness of the flange 3 by an approximately constant thickness d3, over the greater part of the sticking area.
