PROBLEM TO BE SOLVED: To obtain a light deflector in which the vibration of a coil substrate on which a drive coil is set fixedly and of a rotor is reduced. SOLUTION: A driving magnet position detection element 34 which is disposed on the coil substrate of the light deflector and detects the position of the driving magnet from the change of the magnetic pole of the driving magnet is disposed to an area 29B in which the detection timing of the magnetic pole is delayed. Thereby, the excitation timing of the drive coil 28 is delayed, the timing when the magnetic pole generated in the drive coil 28 faces with the magnetic pole of the driving magnet also changes, and thus the magnetic attraction and the magnetic repulsive force generated by the mutual action of magnetic poles can be reduced. |
