Abstract
A tape reel according to an embodiment of the present technology includes: a cylindrical reel hub that includes an outer periphery portion, a tape being wound on the reel hub. The reel hub is formed of a material in which a deformation amount when a load of 300 N is applied radially inward to an axial center of the outer periphery portion is 0.3 mm or less and a water absorption rate is 0.1% or less.
