Abstract: Provided is an optical pickup device that may efficiently reduce an inclination of an objective lens caused by change in ambient temperature. A lens holder holds the object lens and includes a receiving surface portion contacts a lower surface portion of a periphery portion of an objective lens, and a plurality of protrusions that protrude from the receiving surface portion to contact a peripheral side surface portion of the objective lens and are separated from each other. In a state where the objective lens is held on the lens holder, an adhesive is applied to span over a part of the peripheral side surface portion that does not face the protrusions, and a part of the receiving surface portion that does not contact the lower surface portion of a periphery portion of the objective lens, thus the objective lens is fixed on the lens holder by the adhesive.

Abstract: An optical pickup includes an objective lens for focusing a light beam onto an optical disc surface, a bobbin for supporting the objective lens, the bobbin having a first side face and a second side face on the opposite side of the bobbin with respect to the first side face, a first pair of suspension wires and a second pair of suspension wires, each wire having a first end and a second end, each of the first pair of suspension wires being attached to the first side face of the bobbin at the first end, and each of the second pair of suspension wires being attached-to the second side face of the bobbin at the first end, and a base to which each of the first and second pair of suspension wires is attached at the second end, for supporting the bobbin so that the bobbin can swing on the base. The first and second pair of suspension wires are plated in accordance with at least one different plating requirement between the first pair of suspension wires and the second pair of suspension wires.
