An optical deflection device includes a mirror (13a) having a reflection face for deflecting light that enters the reflection face; and a support member (13b, 13c, 13d, 13e, 13f, 13g, 13h, 13i, 13j) to support the mirror (13a), the support member (13b-13j) including a torsion bar (13b, 13c) having one end being continuously connected to the mirror; a beam (13d, 13e) being continuously connected to another end of the torsion bar (13b, 13c); and a plurality of piezoelectric elements (13f, 13g, 13h, 13i) disposed on the beam (13d, 13e) including a first piezoelectric element (13f, 13g) and a second piezoelectric element (13h, 13i). |
