問題がある。[Problems to be Solved by the Invention] The optical fiber connector is required to have high accuracy in order to reduce the connection loss of the optical fiber. When the optical fibers are butted to each other and spliced, the optical fiber ends may escape into the space on the side opposite to the groove, which increases the splice loss. Further, there is a problem that the optical fiber end portion rises up and splice loss increases when dust is present in the groove or when the groove is not accurately formed when the substrate is manufactured.
