An optical deflector includes a support, a frame-like outer movable plate positioned inside the support, two outer torsion bars connecting the support and outer movable plate, an inner movable plate positioned inside the outer movable plate, two inner torsion bars connecting the outer movable plate and inner movable plate, an outer driving coil on the outer movable plate, an outer movable plate driving magnetic field generator, an inner driving coil on the inner movable plate, an inner movable plate driving magnetic field generator, an outer driving coil wiring electrically connected to the outer driving coil, and an inner driving coil wiring electrically connected to the inner driving coil. The inner driving coil wiring extends on the outer movable plate so as to avoid a magnetic field generated by the outer movable plate driving magnetic field generator.
