The present invention provides a lens driving device with a shaking correction function, which does not need magnets for position detection and also cannot reduce driving force during swinging. The lens driving device is configured as follows: a square frame shaped magnet support, each magnet is a cylinder in an isosceles trapezoid shape and is mounted in a corresponding corner in a manner that its long base faces the center of the magnet support, one or two X-direction magnetic force detection mechanisms have detection sensitivity for X-axis direction components of magnetic induction intensity and are mounted on the outer side of the corresponding magnets in a Y-axis direction, and one or two Y-direction magnetic force detection mechanisms have detection sensitivity for Y-axis direction components of magnetic induction intensity and are mounted on the outer side of the corresponding magnets in an X-axis direction.
