Abstract
A lens driving apparatus with a lens portion having at least one lens, a base portion on which an image sensor detecting light coming through said lens portion can be fixed, a driving portion capable of relatively moving said lens portion in a vertical direction to a light axis of said lens portion and in a parallel direction to the light axis of said lens portion with respect to said base portion, and at least three suspension wires connecting a focus portion including said lens portion and said base portion so as to allow a relative movement. The suspension wires are arranged outside a magnet of said driving portion along the vertical direction to the light axis.
