Abstract

A signal compensation line includes at least one of: a first signal compensation line including a first end connected to a main line (3) on a side closer to a first communication device (1) with respect to a first connection point (8-1) counted from the first communication device (1) among connection points (8-1) to (8-3) between the main line (3) and respective first ends of branch lines (5-1) to (5-3), and a second end grounded; or a second signal compensation line including a first end connected to the main line (3) on a side closer to a second communication device (2) with respect to the first connection point (8-3) counted from the second communication device (2) among the respective connection points (8-1) to (8-3), and a second end grounded.
