Abstract
The optical pickup device includes a light-emitting element that emits light, an objective lens that converges light emitted by the light-emitting element on an external optical recording medium, a light-receiving element that receives the light returned from the optical recording medium via the objective lens, a holder that holds the light-emitting element or the light-receiving element, and a casing to which the holder is secured with an adhesive interposed therebetween. The holder has a holder's bonding surface to be bonded to the casing, while the casing has a case's bonding surface facing the holder's bonding surface and to be bonded to the holder. The holder's or casing's bonding surface is provided with adjoining sidewalls that have wall faces forming an angle with the holder's or casing's bonding surface. The holder and casing are adhesively secured to each other with a UV-curable adhesive applied on the holder's or casing's bonding surface.
