Provided are an objective lens driving device capable of strengthening the effective magnetic fluxes of the magnets while preventing increases in size and costs of the device; and an optical pickup apparatus including the same. The objective lens driving device of the invention includes an actuator frame for movably supporting an OBL holder. Four tracking coils are attached to sidewalls of the OBL holder, and four magnets are attached to the back yokes of the actuator frame to be opposed to the tracking coils, respectively. In addition, two of the tracking coils are placed tilting to one of the sidewalls of the OBL holder.
