Claim:
A camera module, comprising: a lens unit which constitutes an optical system of the camera module; a holder which houses the lens unit and is displaceable along an optical axis direction of the lens unit, the holder having a cylindrical shape having upper and lower cylindrical end portions; a coil provided on the holder, the coil being formed from a wound wire having both end portions used as lead wires for supplying an electrical current to the coil; a yoke and magnets provided on the yoke for providing a magnetic field to the coil; a flexible printed circuit board to which the lead wires are connected for supplying an electrical current to the lead wires, the flexible printed circuit board having an insulating sheet portion and a pattern portion; upper and lower leaf springs for supporting the holder so that the holder is displaceable along an optical axis direction of the lens unit, each of the upper and lower springs including an outer annular portion, an inner annular portion provided inside the outer annular portion and attached to one of the cylindrical end portions of the holder, and a plurality of bridge portions coupled between the outer annular portion and the inner annular portion for displaceably supporting the inner annular portion with respect to the outer annular portion; and an imaging element provided below the lens unit, wherein a part of the insulating sheet portion of the flexible printed circuit board is formed into a tongue part which extends in a tongue-shaped manner, wherein the tongue part is arranged in a space between one of the bridge portions of the upper or lower leaf spring and the lead wires so that the bridge portion does not make contact with the lead wires even in the event that the bridge portion is hardly deformed.
