Provided is a reel capable of improving the rigidity of the hub and maintaining the tape characteristics. A single resin layer 36 lying below an aluminum ring 112 in an axial direction of the reel hub 32 and having a wall thickness t2 of 0.8-1.7 mm can suppress the partial rigidity reduction of the reel hub 32. This can suppress the partial characteristic deterioration of a recording tape T wound on the reel hub 32 (partial broadening of the width of the recording tape T, etc.). Besides, crack occurrence can be reduced in the single resin layer 114 of the reel hub 32.
