<p>An optical scanning apparatus (1) for optical scan that oscillates at least partially an oscillating body (5) having a reflective mirror portion (8), to thereby modulate a direction in which the reflective mirror portion causes incident light thereon to be reflected off, is disclosed, the oscillating body comprising: a first spring portion (8, 9), coupled to the reflective mirror portion, and excited to generate a torsional oscillation of the first spring portion; and a plurality of second spring portions (12, 13, 15, 16), coupled to the first spring portion, and coupled to a fixed frame portion (7) of the oscillating body in a bifurcation manner with a bifurcation spacing of the plurality of second spring portions being larger than a width of the first spring portion, the plurality of second spring portions being excited to generate flexural and torsional oscillations thereof. <IMAGE></p> |
