PROBLEM TO BE SOLVED: To provide a signal distributor suitable for distributing a communication signal transmitted to a power line, and to provide a feed through power line communication system equipped with the signal distributor. SOLUTION: The signal distributor 10 is arranged between a parent modem 210 and a plurality of child modems 203 and distributes communication signals from a signal repeater 80, relaying the communication signals being transmitted on the power line between them, to the plurality of child modems 203 being connected with the power line. In particular, a filter section 2 passes a communication signal having a specified frequency out of the communication signals being transmitted/received from/by the signal repeater, and attenuates communication signals having other frequencies. The filter section 2 has a first filter section 2a passing a communication signal having frequency f<SB>1</SB>and attenuating a communication signal having frequency f<SB>2</SB>(f<SB>1</SB>>f<SB>2</SB>), and a second filter section 2b passing the communication signal having frequency f<SB>2</SB>and attenuating the communication signal having frequency f<SB>1</SB>.
