ABSTRACT:
The reel includes a reel hub that is made of a resin material and is formed into a cylindrical shape, an upper flange that is made of a resin material and is extended integrally outward in a radial direction from one end portion in an axial direction of the reel hub, and a reinforcement ring that is integrally disposed radially inside a tape take-up surface of the reel hub by insert molding and reinforces the reel hub in the radial direction. A position of an upper end of the reinforcement ring coincides with a position of an upper end of the tape take-up surface in the axial direction of the reel hub.
