ABSTRACT:
In an optical connection board, a first clad layer is formed on a flat surface of a substrate and a core layer is formed on the first clad layer and is extended in a propagation direction of an optical signal. The core layer is covered with a second clad layer. A termination mirror having a reflection face is so buried in the clad layer as to reflect the optical signal guided in the core layer, to the outside of the optical connection board.
