Disclosed is a method of manufacturing an optical waveguide, capable of easily manufacturing an optical waveguide which can hold an excellent light propagating characteristic irrespective of the kind of a supporting substrate. On a transparent substrate, a peelability promoting film obtained by setting silicone oil and an optical waveguide made of an epoxy resin are sequentially formed. The peelability promoting film promotes the peelability between the transparent substrate and the optical waveguide with sufficient adhesion that it is not peeled off from the transparent substrate during formation of the optical waveguide. Subsequently, after adhering a multilayer wiring board to the optical waveguide via an adhering layer made of a photosetting resin, the adhering layer is irradiated with light so as to be set, thereby fixing the multilayer wiring board to the optical waveguide. When a tensile stress is mechanically applied to the transparent substrate, the transparent substrate is easily peeled off from the optical waveguide together with the peelability promoting film, and the optical waveguide is transferred onto the multilayer wiring board.
