A lens driving apparatus in accordance with the present invention comprises a lead screw rotated by a driving source; a nut plate formed with a female threaded part meshing with a threaded part of the lead screw and adapted to move along the optical axis as the lead screw rotates; a lens holding frame provided to abut against the nut plate while being slidable with respect to a guide shaft extending along the optical axis, for holding a lens; and urging means for urging the lens holding frame against the nut plate. In this lens driving apparatus, the lens holding frame moves along the optical axis as the nut plate provided separately from the lens holding frame moves.
