The suspension wires are arranged outside a magnet of said driving portion along the vertical direction to the light axis. ## Claims ### Claim 1 A lens driving apparatus comprising: a lens portion having at least one lens, a rectangular movable portion including the lens portion, a fixing portion including a circuit board capable of supplying electricity to the movable portion, a first driving portion configured to move the movable portion relatively to the fixing portion along a vertical direction to a light axis, a second driving portion configured to move the lens portion relatively to the fixing portion along the light axis, and a supporting portion connecting the movable portion and the fixing portion so as to allow a relative movement of the movable portion and the fixing portion to the vertical direction to the light axis, wherein a magnet attached to the movable portion is arranged at a corner of the movable portion, and the circuit board in the fixing portion is electrically connected to a coil of the second driving portion through the supporting portion. ### Claim 2 (depends on 1) The lens driving apparatus as set forth in claim 1, wherein the supporting portion is provided at four corners of the lens driving apparatus. ### Claim 3 (depends on 1) The lens driving apparatus as set forth in claim 1, wherein the fixing portion has an image sensor configured to detect a light coming through said lens portion. ### Claim 4 (depends on 1) The lens driving apparatus as set forth in claim 1, wherein a resilient portion connecting to the supporting portion is divided in at least two. ### Claim 5 (depends on 1) The lens driving apparatus as set forth in claim 1, wherein the supporting portion is constituted by at least three or more suspension wires. ### Claim 6 (depends on 1) The lens driving apparatus as set forth in claim 1, wherein the magnet is on a hypothetical line connecting between the supporting portion and the light axis. ### Claim 7 (depends on 1) The lens driving apparatus as set forth in claim 1, wherein a shortest distance between the supporting portion and the light axis is longer than a shortest distance between the magnet and the light axis.
