1. An optical scanning device comprising:
a first structure and
a second structure, wherein
the first structure includes:
a support, wherein the support includes a support body and a flat section connected to the support body and extending further outward from an outer periphery of the support body;
a beam connected to the flat section;
a driver rotatably connected to the flat section with the beam interposed therebetween;
a first columnar body connected to the driver and having a height corresponding to a thickness of the support body; and
a driving section configured to rotate the driver using the beam as an axis,
the second structure includes:
a reflector disposed so as to face the support; and
a second columnar body connected to the reflector and connected to the first columnar body, and
the beam is disposed in a part, opposite to a side where the second structure is disposed, in the support.
