摘要 |
The present invention is to provide an optical circuit board enabling the easy alignment of the positions of a core of an optical pin with the positions of a core of an optical waveguide layer with a simple structure. The optical circuit board comprises an optical wiring layer ( 31 ) having optical waveguides ( 35 ) and the optical pin ( 32 ) is inserted into a hole ( 34 ) formed in the optical wiring layer and cutting a part of the optical waveguide. The optical pin comprises a core ( 2 ) and a clad, and first recesses ( 5 ) are formed in one of its outer surfaces. Projections ( 33 ) used as guides for positioning the optical pin together with the recesses are formed on one of the wall surfaces of the hole.
