<P>PROBLEM TO BE SOLVED: To provide an optical module lens that can maintain original transparency and moldability of thermoplastic transparent resin, and also, has excellent heat resistance against reflow-soldering. <P>SOLUTION: The optical module lens is characterized in that a cured layer composed of thermal-curing or photocuring coating agent is disposed on the surface of a lens-shaped molding molded of the thermoplastic transparent resin, wherein the thickness of the cured layer is 1 to 100 μm, and the TMA thermal deformation temperature of the cured layer is ≥300°C, the thickness ratio of the cured layer expressed by the following expression (1) is in the range of 3-15% at the center of the optical module lens, the expression (1) is shown by (thickness ratio (%) of the cured layer)=(cured layer thickness/lens thickness)×100. <P>COPYRIGHT: (C)2010,JPO&INPIT |
