PROBLEM TO BE SOLVED: To provide an optical scanner that includes a vibration mirror part 41 that has a reflection surface 41a reflecting light emitted from a first light source 31, torsion bar parts 42 and 43 that support the vibration mirror part 41, driving parts 47 that torsionally vibrate the vibration mirror part 41 around the torsion bars 42 and 43, and a housing 50 that accommodates the vibration mirror part 41, torsion bar parts 42 and 43, and driving parts 47; and enable easy adjustment of the mass of the vibration mirror part 41 accommodated in the housing 50 while achieving a simple device configuration.SOLUTION: An optical scanner includes: a mass adjusting unit 70 that is formed on a surface 41b on the opposite side of a reflection surface 41a in a vibration mirror part 41 and configured such that the mass can be removed when irradiated with laser light; and an optical element unit 80 that reflects laser light emitted from a second light source 32 arranged on the outside of a housing 50 to irradiate the mass adjusting unit 70 with the laser light. |
