Abstract
Provided is an optical deflector that detects an arbitrary deflection angle of a mirror part while avoiding the increase in the length of an optical sensor for detection of the deflection angle. An optical deflectorcomprises: a mirror partthat has a flat reflection surfaceand a grooved reflection surface, each of the flat reflection surfaceand the grooved reflection surfacereflecting an incident light; and an actuatortothat reciprocally turns the mirror partabout a rotation axis. The grooved reflection surfacehas a plurality of longitudinal groovesthat extends parallel to the rotation axis. Each longitudinal groovehas a facing inclination surfacethat is parallel to the rotation axisand that has at least an opening-side portion of a facing inclination surface of a V-groove.
