PHOTOELECTRIC WIRING BOARD, PACKAGING BOARD, AND PHOTOELECTRIC WIRING BOARD PRODUCING METHOD

摘要

A photoelectric wiring board (10) which comprises a board (11) formed with a through-hole, and a photo-wiring layer (12) consisting of a core (120) laminated to the board (11) for transmission of light and a clad (121) holding the core (120), wherein the electric wiring board (11) has an electric wiring formed on one surface, and pads (15, 17) electrically connected to the electric wiring and disposed around the through-hole in one surface to install photo-parts, the core (120) having a horizontal waveguide (120a) for horizontal propagation of light along the electric wiring board (11), and a vertical waveguide that is a waveguide crossing the horizontal waveguide (120a) and part of which is disposed in the through-hole to propagate light in a direction normal to the electric wiring board (11).
