Abstract: PROBLEM TO BE SOLVED: To reduce the amount of optical loss at six planes of a core intersection space (typically having a rectangular parallelepiped shape) formed by intersection of a plurality of optical waveguide cores.SOLUTION: In an intersection structure comprising a plurality of cores 2 and a clad 3 that surrounds the cores 2, the same material as that of the cores 2 is added to two planes, i.e., upper and lower planes, of intersection spaces where the plurality of cores 2 intersect (instead of using a clad material). In an alternative intersection structure comprising cores 2 and a clad 3, four planes that divide (isolate) the intersection spaces where the plurality of cores 2 intersect, that is, four discontinuity spaces 6 between the core intersection space and the cores connected thereto, are filled with the same material as that of the clad 3 (instead of using a core material so as to be connected seamlessly).
