Abstract
The tape reel includes the cylindrical portion and a bottom portion having an installation surface on which the cylindrical portion is installed upright. The installation surface has a central surface located on a center side of the bottom portion, and a first inclined surface formed on an outer peripheral portion of the central surface along a peripheral direction of the cylindrical portion and inclined such that a wall thickness of the bottom portion gradually decreases toward an outer peripheral side. A through hole penetrating the bottom portion is formed in the outer peripheral portion, a pair of wall portions are installed upright on the first inclined surface on both sides of the through hole in the peripheral direction, and a second inclined surface having an inclination angle smaller than an inclination angle of the first inclined surface with respect to the central surface is formed on a surface of each of the wall portions, which is connected to the central surface.
