Abstract:
An optical pickup device includes a holder which holds an LD and a light-receiving element and an optical pickup case on which the holder is adhesively fixed via an ultraviolet cure adhesive, and is provided with a through hole on a bonding surface of the holder in order to reduce shrinkage when ultraviolet light is irradiated and to form a blind portion on which the ultraviolet light is not irradiated from a specific direction for adhesively fixing with high position accuracy.
