PROBLEM TO BE SOLVED: To prevent an overcurrent caused by a short circuit in a simple structure and at a low cost. SOLUTION: A separator or a distributor comprises: a printed circuit board with a circuit unit having an input and an output terminals, and at least a distributing circuit and a current-conduction circuit; and a housing storing the printed circuit board. A current-conduction interrupting means is provided in the current-conduction circuit in such a structure that the circuit acts as conductive when the current flows with a level not higher than a predetermined level, and that the circuit is interrupted when a cut-off current flows with the level higher than the predetermined level. The current-conduction interrupting means is formed by etching a metallic thin wire or a printed wiring pattern to interrupt the current-conduction circuit when the cut-off current flows. Further, a high-frequency interrupting coil combined with the current-conduction interrupting means is provided in place of the high-frequency interrupting coil constituting an input-side high-frequency/power-supply separating filter in the current-conduction circuit.
