<p><P>PROBLEM TO BE SOLVED: To provide an optical waveguide and an optical waveguide structure, having superior heat resistance and low water absorption, while suppressing the material cost to be low. <P>SOLUTION: The optical waveguide structure 9 includes an optical waveguide 90 which includes a core layer 93 having a core part 94 and a cladding part 95 having a lower refractive index than that of the core part 94, and cladding layers 91, 92 disposed in contact with both faces of the core layer 93 and having a lower refractive index than that of the core part 93; and conductive layers 901, 902 disposed on both faces of the optical waveguide 90. The cladding layers 91, 92 are made of a norbornene polymer as the main material. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
