PROBLEM TO BE SOLVED: To provide an optical board, a method for manufacturing the optical board, and an optical module structure, by which the manufacturing cost can be reduced.SOLUTION: An optical board 1 includes a substrate 10 including a plate-shaped resin including a first main plane 10a and a second main plane 10b facing each other, and a slit-shaped optical fiber receiving portion 100, and a metal layer 3 provided on the second main plane 10b of the substrate 10, and a wiring pattern 2 consisting of metal and provided on the first main plane 10a. An inclined plane 101 is provided at an end of the optical fiber receiving portion 100 in the substrate 10, a tilt angle &thetas; of the inclined plane 101 with respect to the first main plane 10a is an obtuse angle, and a reflective layer 102 is provided on the inclined plane 101 for reflecting light output from an optical fiber 9 received in the optical fiber receiving portion 100 toward the first main plane 10a. |
