An objective lens driving apparatus for an optical pickup includes a blade on which an objective lens can be mounted, a plurality of elastic support members supporting the blade and capable of elastically moving with respect to the blade, and a servo mechanism driving the blade up and down, left and right, and in a rotational direction. The elastic support members are grouped into pairs arranged to face each other with respect to a center of rotation of the blade, and distances between the elastic support members in the respective pairs are substantially identical. By lessening the difference in the amount of deformation between the elastic support members supporting the blade during tilt control, the elastic support members are less likely to move in undesired directions when vibration is applied.
