ABSTRACT:
An optical pickup device includes: a light source for emitting light in a first wavelength range; an optical element for transmitting the light; a supporting member for supporting the optical element through an adhesive; a first light blocking member for blocking the light emitted from the light source from entering the adhesive when the optical element guides the emitted light to the optical disc; and a second light blocking member for blocking the light reflected from the optical disc from entering the adhesive when the optical element guides the reflected light to the detector unit. In this optical pickup device, at least one of the first and second light blocking member blocks the light in the first wavelength range and transmits light in a second wavelength range.
