Abstract
There is disclosed a light deflector in which both ends of a movable plate is supported to a support substrate by an elastic support portion, a reflection surface is formed on one surface of the movable plate, and the movable plate is torsion-oscillated about a torsion axis of the elastic support portion as a center to deflect an incident light that enters the reflection surface, wherein a recessed portion is formed on at least one side surface of both sides, which is a surface on which the reflection surface is not formed, and between which the torsion axis of the elastic support portion is interposed.
