An optical pickup device having a lens through which light transmits, a holder to which the lens is mounted, a position adjusting member which is mounted on the holder, and a housing to which the holder is mounted has a structure to allow adjustment of a mounting position of a lens assembly formed by mounting the lens and the position adjusting member on the holder when the lens assembly is assembled in the housing. In this manner, the lens can be mounted to the housing with high precision.

Optical pickup device and manufacturing method thereof

An optical pickup device comprises a light emitting element which emits laser light, a photodetector which monitors a state of the laser light emitted from the light emitting element and applies feedback to a control of the light emitting element, and a reflect mirror which allows a portion of the laser light emitted from the light emitting element to be irradiated to the photodetector, wherein a rough surface portion is provided on a surface of the reflect mirror to avoid an erroneous operation of the optical pickup device.
