<p>It is possible to provide a power outlet device capable of easily and optimally making a connection between an indoor power wiring used for power line communications and an electric device including a communication device. A tap unit (3) connected to a power plug (1) via a power cord (2) includes an impedance adjusting unit (30), and power jacks (41, 42, 43, 44) and is contained in a schematically shown tap case (100). The power jacks (41, 42) are connected directly to the power cord (2) while the power jacks (43, 44) are connected to the power cord (2) via the impedance adjusting unit (30). Around an entry on the surface of the tap case (100), color display units (51, 52, 53, 54) are arranged to indicate connection states of the power jacks (41, 42, 43, 44) with the impedance adjusting unit (30).</p> |
