<p>An optical scanning apparatus scanning a light in a specific direction comprises a light source configured to irradiate a light; a diaphragm plate configured to comprise an opening section through which the light from the light source passes; and a holder configured to hold the diaphragm plate. The holder holds the diaphragm plate in a state of curving the diaphragm plate. The diaphragm plate in a curved state elastically deforms and comes into close contact with the holder through elastic deformation force.</p> |
