ABSTRACT:
The invention can obtain an excellent linear property in a focusing direction and a tracking direction and can obtain a stable operation, in an objective lens driving means of an optical pickup. In an optical pickup reading and writing an information with respect to an optical disc by using an objective lens, a movable portion mounting the objective lens thereon is supported by a support member constituted by a pair of flexible printed circuit boards respectively curved in opposite directions in a parallel direction to an optical axis of the objective lens so as to be movable with respect to a fixed portion, in both side surfaces of the movable portion facing with holding the objective lens therebetween.
