ABSTRACT:
To provide an optical pickup device in which an optical parts module is fixedly adhered in a high positional precision to an optical pickup case, such that the adhesion strength can be sufficiently enhanced against a stress to be applied to the adhering faces from a flexible printed circuit board connected to the optical parts module, the present invention forms the adhering faces on at least two portions across the optical axis of the optical parts module, and also forms groove portions on the individual surfaces of the optical parts module and the optical pickup case for the adhering faces.
