SOLUTION: Partition walls 6, which divide the inside of a main body 2 of a cable trough for communication into a plurality of groove spaces 6, are integrally erected on the bottom section of the main body 2. In addition, the top face of a trough cover 3 is curved so that the top face forms spaces 31 having circular arcuate cross sections above the spaces 61, and both leg sections 32 of each curved face are supported by upper end sections 62 and 22 of the sidewalls of each space 61.
