PROBLEM TO BE SOLVED: To provide an optical pickup device wherein a holder holding an LD and a photodetector can be adhesively fixed to an optical pickup case via a UV curing type adhesive with high position accuracy by reducing curing contraction upon irradiation with UV. SOLUTION: In a structure for adhesively fixing the holder holding the LD and the photodetector to the optical pickup case via the UV curing type adhesive, protrusions are provided on an outer peripheral part (on a side of a UV radiation light source) of an adhesion surface of the holder in order to form a part of low intensity of irradiation with UV. Thereby, a part of high intensity of irradiation with UV is first cured to reduce a contraction amount in a direction Z by transfer of the adhesive from an uncured part and then the uncured part is cured.
