摘要：
An optical deflection device includes: a rotor having reflection surfaces on a cirumferential surface thereof; a bearing for rotatably supporting the rotor; a magnet fixed on the rotor; a supporting member for supporting the bearing, on which a radiating fin is integrally formed; and a coil fixed on the supporting member at a position where the coil faces the magnet for forming a magnetic field.
