Abstract
In the optical waveguide board, simultaneously with pattern formation of mirror members at arbitrary positions on a clad layer, guiding patternshaving convex shapes are formed respectively at arbitrary positions on peripheral parts of mirror patterns, and the mirror patternsare worked into tapered shapes. Next, in a state that a mask memberhaving through holes at desired positions, and the guiding patternsare guided by mating, a metal film is formed on surfaces of slope partsof the mirror patterns and the guiding patterns. Furthermore, in a state that the guiding patternsand the photomaskare guided, wiring core patternsare formed on the clad layeradjacent to the mirror patterns
