A power line carrier communication device functioning as one of the slave units connected by bus to the power line connected to the master unit,
A receiver for receiving a signal flowing in the power line;
A demodulator that demodulates the received signal of the receiver;
A control unit,
The receiver is
A first signal path that is installed between the power line and the demodulator and blocks a signal having a frequency other than the first frequency band;
A second signal path that is installed between the power line and the demodulator and blocks a signal of a frequency other than the second frequency band that does not overlap with the first frequency band;
First switch means provided in the first signal path;
Second switch means provided in the second signal path,
The control unit turns on the first switch means and turns off the second switch means when waiting for the repeater slave unit to operate and when communicating with other slave units, and communicating with the master unit. It said first switching means off, the second to that power line communication device, wherein the turning on the switching means when performing.
