Abstract
The purpose of the present invention is to provide: a material from which a cured article can be produced, in which the cured article has small absorption (low optical absorption loss) in a near infrared region that is employed in optical communications, excellent heat resistance and excellent productivity (UV curability); and an optical waveguide and an optical adhesive agent each produced using the material. More specifically provided is a curable resin composition characterized by containing the following components (A) to (C) as essential components ((A) a polysiloxane resin having at least one reactive group 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).
