Optical composites and their manufacturing methods

Abstract

[Problem] To provide an optical composite molded article and a method for manufacturing the same, which can prevent problems when manufacturing optical articles by inserting a composite sheet with an optical functional layer and a protective layer onto a substrate. This is done without relying on special molding methods such as compression molding or injection compression molding. [Solution] The optical composite molded article (1) is formed by combining a composite sheet (10) and a substrate (20). The composite sheet (10) includes: a first protective layer (11) on the surface side, a second protective layer (12) on the back side, and an optical functional layer (13) sandwiched between the two protective layers. The substrate (20) supports the composite sheet (10) from the back side. The first thickness (L1) of the first protective layer (11) is 0.05~0.30 mm, and the second thickness (L2) of the second protective layer (12) is 0.30~0.70 mm.
