Molded optical component, handling method, and assembling method

摘要

An objective lens for use in an optical pickup apparatus for conducting recording and/or reproducing information for an optical information recording medium, has a lens section shaped in an approximate circle and including a flange section; and a connecting section integrally provided to the lens section. The objective lens satisfies the following conditional formulas: 0.5<=A<=2.0, 0.3A<=B<=1.7A where A is a diameter of the lens section when the lens section is viewed from an direction of an optical axis, and B is a width of the connecting section when the connecting section is viewed from the direction of the optical axis.
