Abstract

An object of the present invention is to provide a material that has small absorption (low light absorption loss) in the near-infrared region used in optical communication, has excellent heat resistance, and, in addition, can produce a cured article having excellent productivity (UV curability) and also to provide an optical waveguide and an optical adhesive made from the material. Specifically, provided is a curable resin composition containing components (A) to (C) as essential components: (A) a polysiloxane resin having one or more reactive groups selected from the group consisting of a (meth)acryloyl group and a styryl group; (B) a (meth)acrylic acid derivative having a structure represented by General Formula (1); and (C) a radical polymerization initiator.
