PROBLEM TO BE SOLVED: To reduce an area of a circuit board mounting a waveform shaping circuit to be arranged inside a branching connector and aim at downsizing of the branching connector. SOLUTION: For the branching connector 10 to be provided at a position at which a plurality of branched lines are connected from a trunk line, a circuit board equipped with a conductive pattern of trunk-line wires 21 and branched line wires 22 is housed in a connector housing 11. The trunk-line wires 21 are connected with branched line wires 22 through a waveform shaping circuit 25 connecting resistors and coils in parallel, the waveform shaping circuit 25 has a gap each provided between the branched line wire 22 and the trunk-line wire 21, and a conductive adhesive 26 is applied to each gap to make up a resistance layer, and at the same time, a chip coil 27 is arranged on the surface of the resistance layer, electrodes at either end of the chip coil 27 are firmly adhered to the conductive adhesive 26 to make up a parallel circuit of the resistor and the coil. Further, the circuit board 20 has terminal materials 31 for the trunk line connected to the trunk-line wires 21 and terminal materials 32 for the branched lines connected to the branched line wires 22 set in protrusion.
