<P>PROBLEM TO BE SOLVED: To obtain an optical pickup in which position adjustment of a detection lens can be performed accurately in spite of simple constitution. <P>SOLUTION: The optical pickup has a lens holder 61 holding a detection lens 60 and an optical base 50 receiving the lens holder 61; the lens holder 61 has a projecting part 62 which is projected at a position being deviated to one direction from the center of the detection lens 60 in the direction being orthogonal to an optical axis direction of the detection lens 60 more than a main body of the lens holder 61, and to which an adjusting tool 70 can be abutted, and in the projecting part 62, an abutting part coming into line-contact in the direction being parallel to the optical axis is formed at a receiving plane 52 of the optical base 50. <P>COPYRIGHT: (C)2010,JPO&INPIT |
