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.
