PURPOSE: To provide the biaxial driving device which is small in size and light in weight and can make simultaneous driving in biaxial directions with one set of unit not requiring positional adjustment between the driving devices by driving an object to be driven by using coil groups for electromagnetic driving, etc., and providing 4 pieces or integer times 4 pieces of coils disposed with the coil groups for electromagnetic driving on four sides.

CONSTITUTION: A gimbal spring 1 as an elastic supporting member for supporting a reflection mirror 1 as the object to be driven regulates the deviation within a plane. The coils 4a, 10a for electromagnetic driving formed by winding wires having low resistance values plural times to an approximately rectangular shape are bent approximately perpendicularly on their one side and are disposed to face each other to form one set. These coils are disposed in ≥2 sets and the total number of the coils 4a, 10a consists of integer times 4. A moving yoke consisting of a ferromagnetic material concentrates the magnetic fluxes generated by stationary magnets 5 and shuts off the leakage thereof to the outside. The driving of the reflection mirror 1 as the object to be driven is controlled simultaneously in the biaxial directions by means of one set of the magnetic circuit system with high accuracy in such constitution.
