PROBLEM TO BE SOLVED: To provide a high frequency signal supplying device capable of supplying a high frequency signal to all power lines of a single-phase circuit and a multi-phase circuit in a well-balanced state and preventing the supplied high frequency signal from flowing to a power supply side. SOLUTION: The present invention relates to a high frequency signal supplying device for supplying a high frequency signal outputted from a high frequency signal output device to a power supply line for supplying low frequency AC power from a power supply side to a power demand side while using at least a pair of power lines, wherein a secondary induction coil is connected to each of the paired power lines, the high frequency signal outputted from the high frequency signal output device is supplied to a primary induction coil electromagnetically coupled with the secondary induction coil, and one power line at a power supply side rather than the secondary induction coil and the other power line are connected by a capacitor capable of obtaining high impedance equal to or more than a predetermined lower limit value with respect to the low frequency AC power and obtaining low impedance less than or equal to a predetermined upper limit value with respect to the high frequency signal.
