<P>PROBLEM TO BE SOLVED: To provide an optical pickup device that may efficiently reduce an inclination of an objective lens caused by change in ambient temperature. <P>SOLUTION: A lens holder 2 holds the objective lens 1 and includes a receiving surface portion 2b coming into contact with a lower surface portion of an outer periphery portion 1c of the objective lens 1, and a plurality of protrusions 2c that are provided so as to protrude from the receiving surface portion 2b to come in contact with an outer peripheral side surface portion 1e of the objective lens 1 and are provided separated from each other. An adhesive 3 is applied to span over a part of the outer peripheral side surface portion 1e that does not face the protrusions 2c, and a part of the receiving surface portion 2b, thus the objective lens 1 is fixed on the lens holder 2 by the adhesive. <P>COPYRIGHT: (C)2011,JPO&INPIT |
