Abstract
An optical scanning device includes a first scanning driving unit and a second scanning driving unit. The first scanning driving unit includes a scanning mirror and a frame structure supporting the scanning mirror. The first scanning driving unit is configured to cause the scanning mirror to rotate about a first rotation axis by means of deformation of the frame structure. The second scanning driving unit includes a rotation holder supporting the first scanning driving unit and a supporting shaft. The second scanning driving unit is configured to cause the rotation holder to rotate about the second rotation axis. The frame structure includes a pair of beams provided so as to sandwich the scanning mirror in a direction of the first rotation axis, and a pair of base portions provided on sides of respective beams of the pair of beams opposite to the scanning mirror. Each of the pair of base portions has an elongated shape elongated in a direction of the second rotation axis, and is deformable.
