<p><P>PROBLEM TO BE SOLVED: To provide an optical substrate in which damage is not liable to occur even in physical connection, and to provide a manufacturing method of the substrate. <P>SOLUTION: The optical substrate 50 is provided with a substrate body 52 and optical wiring 11 (optical waveguide core) imbedded in the substrate body 52. An incident/existing end face 12, situated at the end of the optical wiring 11, faces the end face 54 of the substrate body 52. The incident/exiting end face 12 is deflected inside the substrate body 52 from the end face 54 thereof. A recessed part 56 is provided in the end face 54 of the substrate body 52, while the incident/exiting end face 12 constitutes the bottom face of the recessed part 56. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
