PROBLEM TO BE SOLVED: To provide a drive device that has high accuracy in positional relationship between a drive lever (a drive member) and a mounting plate. SOLUTION: The drive device is provided with a rotor unit having a cylindrical magnet 1 of which the outer peripheral face is circumferentially divided so as to be alternately magnetized to different poles and which absorbs laser light, a stator 6 that faces the outer peripheral face of the magnet 1 and has a magnetic pole part 6a excited by a coil, a drive lever 7 fixed to a rotary shaft of the rotor unit so as to integrally rotate with the rotor unit and made of a laser-light transmitting resin, and a mounting plate 8 arranged further externally than the drive lever 7 so as to determine the position of the stator and made of a laser-light transmitting resin. Laser light made to transmit through the mounting plate 8 is irradiated at the position where the drive lever 7 and the magnet 1 overlap with each other so as to fix the drive lever 7 to the rotary shaft of the rotor unit.
