Abstract
A polygon mirror includes a reflective surface group having n number of reflective surfaces (M(), . . . , M(n)) formed individually as outer peripheral side faces, a flat portion which shuts one end portion of the reflective surface group, and n number of pin gate traces (L(), . . . , L(n)) which are provided on the flat portion, correspond to the n number of reflective surfaces, individually, and are kept individually at distances from edge portions at which the reflective surfaces cross the flat portion. There are conditions DM()>DL()/, . . . , DM(n)>DL(n)/and DM()>DL(n)/, . . . , DM(n)>DL(n−1)/, where DM(n) is a shortest distance from an edge portion at which the reflective surface M(n) and the flat portion cross each other to the pin gate trace L(n) and DL(n) is a shortest distance between the pin gate trace L(n) and the pin gate trace L().
