| titleOfInvention | Film optical waveguide |
| abstract | The present invention provides a film-like optical waveguide that can be produced with a low environmental load because the photocurable resin composition has high alkali developability, and has excellent bending durability and transmission characteristics. A film-shaped optical waveguide includes a lower clad layer, a core portion formed on the upper surface of the lower clad layer, and an upper portion formed by laminating the lower clad layer and the core portion. It consists of a cladding layer 22. At least one of the core portion 20, the lower clad layer 12, and the upper clad layer 22 includes (A) (a) a polyol compound, (b) a polyisocyanate compound, (c) a carboxyl group-containing diol compound, and (d) a hydroxyl group. A photocurable resin containing a urethane (meth) acrylate oligomer containing a urethane (meth) acrylate oligomer having a number average molecular weight of 1,500 or more, which is a reaction product of the (meth) acrylate compound, and (C) a photopolymerization initiator It consists of the hardened | cured material of a composition.
