Abstract
A tape reel includes: a first flange; a second flange; and a reel hub. The reel hub includes a first end portion formed integrally with the first flange, a second end portion to which the second flange is bonded, and an outer peripheral surface on which a magnetic tape is wound. The outer peripheral surface of the reel hub has a first outer peripheral region and a second outer peripheral region. The first outer peripheral region expands in diameter from the first end portion toward the second end portion. The second outer peripheral region expands in diameter from the first outer peripheral region across the second end portion and forms a ridge line portion having a shape projecting radially outward of the hub portion on a boundary between the second outer peripheral region and the first outer peripheral region.
