Abstract:
1. An optical pickup device comprising: electronic components including a light-emitting element configured to emit a laser beam and a light-receiving element configured to receive a laser beam reflected by an optical recording medium; an optical element forming an optical path to guide the laser beam emitted by the light-emitting element to the optical recording medium and to guide the laser beam reflected by the optical recording medium to the light-receiving element; a housing where the electronic components and the optical element are mounted, the housing including, an objective lens driver unit including an actuator to drive an objective lens, and being fixed to the principal surface portion of the housing; a first circuit board disposed on the principal surface portion of the housing so that a portion of the first circuit board is exposed in the opening at the corner portion of the housing; and a second circuit board connected to one of the electronic components and attached to the housing so that at least part of the second circuit board is disposed in the opening, the portion of the first circuit board exposed in the opening being connected via an electrically-conductive binder to the part of the second circuit board disposed in the opening, wherein an inner-side part of a protruding end portion of the external sidewall near the second circuit board is formed as a cut surface.
