Apparatus for dualizing a communication bus dualizes a communication bus in a dualized communication node, and prevents a service interruption even if either one communication bus occurs a malfunction. The apparatus include: a plurality of processors(1,2)(5,6)(9,10); a plurality of nodes(3,4)(7,8)(11,12) each connected to the processors(1,2)(5,6)(9,10); a first communication bus(21) connected to every one node among the nodes(3,4)(7,8)(11,12), for achieving a selective communication of each processors(1,2,5,6,9,10); a second communication bus(22) connected to every another node not connected to the first communication bus(21), for achieving a selective communication of each processors(1,2,5,6,9,10); and a communication bus interchange part(23) connected between the first and second communication buses(21,22), for performing an interchange function about the first and second communication buses(21,22).
