Field: Optics (Instruments)
Classification: CPC B  G | IPC B  G

Claim 11:
12. An optical scanner comprising:
a light source irradiating light;
a mirror part reflecting the light irradiated from the light source;
a substrate made of metal and comprising:
a pair of beams each having a first end and a second end,
a support supporting the first end of each of the pair of beams, and
a torsion part swingably supporting the mirror part;

a driving source provided on the support and generating a plate wave that swings the mirror part; and
a vibration suppression part suppressing vibration transmitted to the pair of beams by abutting against the pair of beams, wherein
the torsion part extends in a second direction orthogonal to a first direction in which the pair of beams extends in a direction along a surface of the mirror part, and is connected to each of the pair of beams;
the vibration suppression part is configured to suppress the vibration transmitted to the pair of beams by abutting against the pair of beams at a position between a second mirror end among ends of the mirror part that is opposite a first mirror end near the support and the torsion part in the first direction.
