PROBLEM TO BE SOLVED: To miniaturize an optical device by moving an optical component perpendicularly to the surface of a base boy and to achieve a reliable self-sustain function with simple structure. SOLUTION: A leaf spring structural part 3 which supports the optical component 4 is supported in the form of a cantilever on the upper face of the base body 2, and a pair of slide parts 5 are provided at both sides in the width direction of the leaf spring structural pat 3. Since the side face of the slide part 5 on the side of the leaf spring structural part 3 acts as am action face 5b formed into a tilt face, the slide part 5 gets under the leaf spring structural part 3 while elastically deforming the leaf spring structural part 3 when the slide part 5 moves toward the leaf spring structural part 3, and thus the slide part 5 supports the leaf spring structural part 3 by the upper face 5a of the slide part.
