Summary: | PROBLEM TO BE SOLVED: To provide an optical waveguide excellent in transmission properties and long-term stability of the properties and to provide a method for manufacturing the optical waveguide. SOLUTION: In the optical waveguide comprising a lower clad layer, a core portion and an upper clad layer, at least one selected from the lower clad layer, the core portion and the upper clad layer is a cured body of a radiation- curable composition comprising (A) a copolymer (having alkali solubility) comprising (a) (5-50 wt.% component comprising) a radical polymerizable compound having a carboxy group, (b) (15-60 wt.% component comprising) a radial polymerizable compound having no carboxy group and (c) (5-80 wt.% component comprising) another radical polymerizable compound, (B) a compound having two or more polymerizable reactive groups per molecule and (C) a radiation polymerization initiator.
