PROBLEM TO BE SOLVED: To provide a camera module in which an influence by variation of intervals between magnets and magnetic detection elements is reduced, and which includes position detectors which have achieved precision position detection and miniaturization.SOLUTION: A camera module includes: a first position detector 100X for detecting a position of a lens 11a in a first axial direction; a second position detector 100Y for detecting a position thereof in a second axial direction; and a third position detector 100Z for detecting a position thereof in a third axial direction. Each position detector includes a lens position detection unit for detecting the position of the lens on the basis of first magnets 12X/12Y/12Z mounted on a lens barrel 11b; second magnets 13X/13Y/13Z arranged in positions opposing to the first magnets; magnetic detection elements 14X/14Y/14Z arranged between the first magnets and the second magnets, and relatively moving with respect to the first magnets and the second magnets; and output of the magnetic detection elements. |
