Abstract
The present invention aims to provide a lens driving device which can prevent a lens support from being suspended in an inclined state and can correspond to energizing amount and carry out appropriate linear movement action. A front side primary coil and a rear side primary coil are respectively wound around an axis parallel to an optical axis in a manner of being coaxial to a secondary coil and are combined with each other through electromagnetic induction. The secondary coil is such disposed that its two coil terminals are connected with two ends of a diode respectively. The secondary coil and a permanent magnet assembly are arranged opposite to each other at an interval along the radial direction and a driving current is supplied to the primary coils.
