PROBLEM TO BE SOLVED: To provide a light deflector capable of suppressing reduction of a deflection angle of the light deflector, and improving strength of an actuator.SOLUTION: A light deflector A1 comprises outside piezoelectric actuators 101, 102 for oscillating a reflection surface 1b around a second axis X2. On a coupling part 41 for coupling piezoelectric cantilevers 31-35 of the actuators 101, 102, a rib 42 provided on the coupling part is provided in a projecting state over a range wider than a range of a gap 43 between two piezoelectric cantilevers in a first direction y. |
