<P>PROBLEM TO BE SOLVED: To provide an objective lens drive device allowing easy soldering works of suspension wires with high accuracy and reduction of manufacturing cost and an optical pickup including the objective lens drive device. <P>SOLUTION: The objective lens drive device includes: a lens holder mounted with an objective lens therein; a plurality of coils for driving mounted on the lens holder; connection substrates mounted on both side surfaces of the lens holder; and a plurality of suspension wires having ends connected to the connection substrates to operably support the lens holder. In the objective lens drive device, a plurality of pairs of wire connection electrodes for connecting the suspension wires and coil connection electrodes electrically connected to the wire connection electrodes to connect terminal lines of the coils are arranged side by side in an optical axis direction of the objective lens on the connection substrates, and the wire connection electrodes and the coil connection electrodes are formed into symmetrical shapes with respect to a central axis parallel to the optical axis direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
