    摘要: PROBLEM TO BE SOLVED: To provide an optical pickup device capable of interchanging three types of optical disks of BD/DVD/CD having a plurality of information recording layers with a common objective lens regardless of low cost, and an optical information recording and reproducing device.SOLUTION: If the objective lens of the optical pickup device is used, aberration can be changed in an under (insufficient correction) direction when a wavelength fluctuates to a long-wavelength side. Consequently, aberration that occurs when the temperature of the optical pickup device goes up can be suppressed. Since an objective lens that can maintain stable performance even during temperature change can be provided even in the case that the objective lens is made of plastic, a temperature characteristic during the use of a second optical disk can be made satisfactory. As a result of this, a factor that should displace a coupling lens in an optical axis direction during the use of the second optical disk is eliminated, and the optical pickup device can record/reproduce information to/from an information recording surface of the second optical disk satisfactorily even with the coupling lens fixed.

    摘要: PROBLEM TO BE SOLVED: To provide a lens unit and its manufacturing method capable of precisely positioning and incorporating the lens into a holder regardless of geometric accuracy of the lens side face.SOLUTION: A lens 10 and a holder 20 are connected without having portions positioned each other in relation to a perpendicular direction to an optical axis OA. If geometrical dimensional accuracy of a side face 10c of the lens 10 set at the perpendicular direction to the optical axis OA is low, the lens 10 can be fixed in a precisely positioned state to the holder 20. In a lens unit, the lens and the holder are joined by an adhesive agent. In this case, the lens 10 and the holder 20 can be fixed strongly and moreover, a relative position of the lens 10 and the holder 20 can be easily arranged by the thickness of an adhesion part 41, and the lens 10 and the holder 20 can be relatively and precisely positioned and fixed.
