Abstract: A power line carrier communication reception circuit which can precisely receive a signal to be superimposed at such a signal level that leakage of an electromagnetic wave does not cause a problem while employing a simplified configuration is provided.The power line carrier communication reception circuit may include an amplifier which is connected to a power line and amplifies a received signal to be superimposed on the power line; two capacitors which are connected in series between both power sources of the amplifier; and a clipper circuit which connects connection points of these capacitors to the power line and limits the received signal in a predetermined range of a reference voltage between the capacitors, and in which the amplifier compares the signal limited by the clipper circuit and the reference voltage and amplifies the signal.
