ABSTRACT:
A lens and combination lens able to suppress deviation of an optical axis of a lens occurring at the time of combination and able to be adjusted at a high precision, a method of producing the combination lens, and an optical pickup device and an optical disk drive mounting the combination lens thereon are provided. A first lens L1comprising a lens body1where one surface on an incident side or an emitting side of light is a flat surface and the other surface parallel to the surface formed as the flat surface is a structural element and a second lens L2comprising a lens body2where one surface on an incident side or an emitting side of light is a flat surface and the other surface parallel to the surface formed as the flat surface is a structural element are adhered together. The combination lens is used as the object lens for an optical pickup device and an optical disk drive.
