Abstract
Provided is a polygon mirror that includes a resin member including a first surface, a second surface opposite to the first surface, a through-hole extending from the first surface to the second surface, an inner side surface, which intersects with the first and second surfaces, surrounding the through-hole, outer side surfaces, each of which intersects with the first and second surfaces on an opposite side of the inner side surface, and a die piece division line surrounding the through-hole and disposed on the second surface. The second surface intersects with the individual outer side surfaces at intersection lines. The intersection lines include first and second intersection lines intersecting with the first intersection line at an intersection, which is a first corner portion. The die piece division line is provided closer to the through-hole than a first midpoint between the inner side surface and the first corner portion.
