Abstract
The disclosure discloses a tape roll that winds a tape with a minimum radius R. The tape before being wound includes a flexible material layer. The flexible material layer includes flat plate-shaped reflectors inside and having a thickness T. On condition that a flexural modulus of the reflectors is G, a bending strength of the reflectors is A, and an average particle diameter of the reflectors is 2L, the reflectors satisfy the following relationships R/L{1−cos(L/R)}<A/G, and 2L>T.
