PROBLEM TO BE SOLVED: To realize a compact, lightweight and low-profile objective lens driving device, in which vibration due to the driving force caused by electromagnetic force of a magnetic field and a coil can be suppressed. SOLUTION: The objective lens driving device is provided with a yoke 27, a plurality of magnets 25, 35 connected to the yoke 27 via a viscoelastic member so as to separate from the yoke 27 by a prescribed distance, and a plurality of coils 23, 24 fixed to a lens holder 22, wherein the lens holder 22 is moved by the electromagnetic force action between one magnet 23 of the plurality of magnets 23, 24 and one coil of the plurality of coils 25, 35 which pair with it.
