PROBLEM TO BE SOLVED: To provide an optical waveguide wiring substrate assembly that facilitates connection of a waveguide element such as an optical fiber and that excels in flatness, and also to provide an optical coupling unit in which a waveguide element is connected to the optical waveguide wiring substrate assembly. SOLUTION: This is an optical waveguide wiring substrate assembly 50 having an optical waveguide wiring substrate 30 and a connecting member 40. The optical waveguide wiring substrate is provided with a substrate end part 32 in which the end face 36 of a waveguide is exposed and formed. The connecting member is provided with a first connecting part 42 to which the substrate end part is connected and a second connecting part which has a waveguide 46 and which is connected with the end of a waveguide element 90 having an end part 96 with the waveguide end face 94 exposed and formed. In the optical waveguide wiring substrate assembly, a light guiding part 46 is installed between the first and second connecting parts, and the end faces 47, 48 of the light guiding part are exposed and formed in the first and second connecting parts. Also, in the assembly, the substrate end part is connected to the first connecting part, the end face of the waveguide and that of the light guiding part are optically connected. The invention further refers to the optical coupling unit in which a waveguide element is connected to the optical waveguide wiring substrate assembly. COPYRIGHT: (C)2006,JPO&NCIPI
