Optical pickup device and method for manufacturing the same

An optical pickup device comprising:

• a holder for holding at least one of a laser diode and a light-receiving element;
• and
• a casing of an optical pickup having the holder fixed thereto via an adhesive;
• wherein a space is provided between the adhesive and an optical beam shielding section provided at the peripheral region of the bonding surface of the holder.

A method for manufacturing an optical pickup device, the manufacturing method comprising:

• a step of providing a casing of an optical pickup, a holder for holding at least one of a laser diode and a light-receiving element, the holder being formed to include protrusions at peripheral sections of a surface other than a bonding surface opposed to the casing, and an ultraviolet-curable adhesive put in a clearance between the holder and the casing of the optical pickup;
• a first curing step of irradiating the ultraviolet-curable adhesive with ultraviolet radiation with the holder and the casing of the optical pickup held so that the ultraviolet-curable adhesive may be cured;
• and
• a second curing step of curing the section of the ultraviolet-curable adhesive that has been irradiated with reduced ultraviolet radiation by the protrusions in the first curing step.
