Zusammenfassung:PROBLEM TO BE SOLVED: To provide a motor-integrated compact camera module capable of adjusting a focus.SOLUTION: A housing 104 includes a plurality of electromagnet coils 210 functioning as the stator of a motor. A lens barrel 108 includes a plurality of ferrite elements 208 functioning as the rotor of the motor. The housing includes an inclined surface 212. The inclined surface is freely slidably engaged with the rear surface of an operation ring 106. When the lens barrel is rotated by an electromagnet force between the ferrite element and a winding, a distance between a lens assembly and an image capture device is changed by the inclined surface, to make the focus adjustable.
