A camera module is provided to manufacture the camera module easily while reducing size and volume of the camera module by moving a location of a lens by using a shape memory alloy transformable in a length direction. An image sensor chip(120) has an image sensing part. A lens(150) concentrates light to the image sensing part. A lens barrel(160) fixes the lens. An external housing(180) has the images sensor, the lens, and the lens barrel inside to form an optical path between the lens and the image sensing part of the image sensor chip. A focus moving unit(190) moves the lens and the lens barrel to the image sensor chip for changing a focal distance between the image sensing part and the lens by a change of the focus moving unit in a length direction. The focus moving unit is made of a shape memory alloy. |
