An optical scanning apparatus that scans a light beam from a light source includes: a movable portion and a fixed portion. The movable portion includes: a rotating member, which is capable of rotating about a rotation axis being parallel with an optical axis of the light beam, has an open hole through which the light beam passes, and is provided with a first coil; and a mirror that is provided to the rotating member, electrically connected with the first coil, and reflects the light beam that passes through the open hole of the rotating member in a variable angle with respect to the optical axis of the light beam. The fixed portion includes: a magnetic member; and a second coil capable of supplying an electromagnetic field to the first coil. One of a part and a whole of the magnetic member is made of a magnetic material and the magnetic member serves as a magnetic core of the second coil.
