An optical fiber scanning device includes a housing, an optical fiber configured to emit light, a magnet disposed on the optical fiber, four drive coils configured to drive the optical fiber by applying to the magnet a magnetic field generated by a received drive power signal, and four detection coils configured to output an induced electromotive force signal corresponding to variation of a magnetic field, wherein the drive power signal is controlled based on the induced electromotive force signal, and four coil assemblies each including any one of the drive coils and any one of the detection coils are disposed at rotationally symmetrical positions so as to interpose the optical fiber among the four coil assemblies.
