ABSTRACT:
A reinforcement ring is insert-molded as an insert body on a reel hub of a reel around which recording tape is wound. The reinforcement ring includes a metal ring at least whose inner peripheral surface is covered by a resin layer. The clearance between the reinforcement ring and a mold during reel molding can be reduced, and the amount of eccentricity of the insert body with respect to the reel hub can be reduced.
