PURPOSE: A signal connection apparatus for power line communication is provided to connect signals without bringing a power line communication unit into contact with power lines by inducing signals through magnetic cores in an electromagnetic induction method. CONSTITUTION: A signal connection apparatus for power line communication is comprised of a pair of power lines(10,11), a pair of magnetic cores(20,21), and a signal line(30). The power lines(10,11) are used to supply power for power line communication. The magnetic cores(20,21) are respectively installed at the outer circumferences of the power lines(10,11). The signal line(30), wound on the magnetic cores(20,21), is connected with the signal terminals of a power line communication unit(S).
