Abstract
Provided are an optical transmission structure having a high degree of flexibility in the design of an optical waveguide and a method for manufacturing the optical transmission structure, and also an optical transmission module. An optical transmission structure includes a main substrate (), a cladding member (), and core members (). The main substrate () has a through hole () penetrating therethrough in a thickness direction thereof. The cladding member () is disposed inside the through hole () and has a plurality of optical waveguide holes () penetrating therethrough in a thickness direction thereof. The core members () are disposed inside the plurality of optical waveguide holes (), respectively, and have a refractive index larger than the cladding member ().
