The present invention solves the problem of difficulties with miniaturization and positioning magnets in suitable locations due to coils being disposed in such a manner as to surround a mirror in a drive device such as a MEMS scanner in which a driven object such as a mirror is made to rotate. These drive devices (103, 104) are provided with: a second base (110-2) that rotates around the X-axis via first elastic parts (120a-1, 120b-1) inside a first base (110-1); and a driven part (130) that rotates around the Y-axis via second elastic parts (120a-2, 120b-2) inside the second base. The driven part is disposed on the outsides of the windings of a first coil (140a) and a second coil (140b), which are disposed on the second base with the driven part therebetween. In addition, magnetic field applying parts (161, 162), which each apply a magnetic field to each coil, are disposed in such a manner as to be offset from each other in the X-axis direction or the Y-axis direction. |
