LIGHT-SHIELDING FILM

摘要

The present invention relates to a light-shielding film excellent in light-shielding property and heat resistance, a production method of such a film, and a lens unit including such a film. The present invention is a light-shielding film including an organic resin and a black material, wherein the organic resin is a cured product of a curable resin or a thermoplastic resin having a glass transition temperature of 150 degrees C or more. The present invention is also a production method of a light-shielding film comprising an organic resin and a black material, wherein the production method includes a surface roughness-forming step of forming a rough surface of the light-shielding film by a transfer method. Further, the present invention is a lens unit including the light-shielding film and a lens, wherein the lens unit has reflow resistance.
