PROBLEM TO BE SOLVED: To provide a lens holder which can be housed in a thin body. SOLUTION: The lens holder includes a first lens frame 70 supporting a first lens group 101, a second lens frame 80 supporting a second lens group 102, and cam barrels 10, 20 and 30, and is operated to include a first variable power range and a second variable power range, thereby a distance between the first lens group 101 and the second lens group 102 in a direction of an optical axis L is changed. In the first variable power range, in a state where the first lens frame 70 is supported by the first cam barrel 10 and the second lens frame 80 is supported by the second cam barrel 20, they are moved back and forth along the optical axis L by the third cam barrel 30, whereby a distance between the first lens group 101 and the second lens group 102 is changed. In the second variable power range, in a state where the first lens frame 70 and the second lens frame 80 are supported by the first cam barrel 10, a distance between the first lens group 101 and the second lens group 102 is changed.
