A leaf spring for an auto-focus actuator of a compact optical lens is provided to improve reliability of a drop test by dispersing external impact applied to a connection curved part to inner and outer curved parts formed at a tension bar. A leaf spring(50) inserted into an auto-focus actuator of a compact optical lens includes a spring fixing part comprising outer and inner fixing units(22,21) formed at the outer and inner sides, respectively and a tension bar(30) disposed between the outer and inner fixing units and composed of an outer curved part(32) protruded outward, an inner curved part(31) protruded inward, and a connection curved part(33). The curvature of the outer curved part is larger than that of the inner curved part.
