摘要： To provide an optical pickup device adapted such that for adhesion fixing of a holder for holding an LD or a light-receiving element to an optical pickup casing via an ultraviolet-curable adhesive, curing shrinkage during ultraviolet irradiation can be reduced and adhesion fixing achieved with high positioning accuracy. In a structure for adhesion fixing of a holder for holding an LD or a light-receiving element to an optical pickup casing via an ultraviolet-curable adhesive, since protrusions are provided at peripheral sections (UV irradiation light source side) on a bonding surface of the holder, a section exposed to strong UV light is first cured, then after the adhesive has moved from an uncured section, the amount of shrinkage of the first cured section in a Z-direction is reduced, and the uncured section is cured.
