Abstract
An optical pickup apparatus comprises a photo detector that receives light reflected from a medium; and a housing that is mounted with the photo detector. The photo detector is fixed to the housing with the use of an adhesive to mount the photo detector on the housing. The housing is provided with a displacement preventer that prevents displacement of the photo detector or the adhesive relative to the housing. The displacement preventer has fixing portions that extend along a plurality of directions. The photo detector is mounted on the housing by applying the adhesive to the displacement preventer.
