PROBLEM TO BE SOLVED: To provide a camera module capable of securing the stable load characteristic of a leaf spring and the stable thrust of a holder in a magnetic circuit. SOLUTION: An upper leaf spring 5 has: an outer annular portion 5a; an inner annular portion 5b provided to be displaceable with respect to the outer annular portion 5a and also fixed to a holder 9; and a plurality of bridge portions 5c supporting the inner annular portion 5b with respect to the outer annular portion 5a, and is equipped with a bridge portion supporting member 4 for partially supporting the bridge parts 5c of the upper leaf spring 5 so that the load characteristic of the upper leaf spring 5 can be changed. By rotating the bridge portion supporting member 4 in a clockwise direction, an overlapping part (mark A) between an extending part 4c and the bridge portion 5c is increased, so that a spring constant of the upper leaf spring 5 is apparently increased.
