PURPOSE:To increase the coupling loss and to prevent the leakage of a signal by providing a distribution transformer where a couple of coils whose winding ratio is nearly 1:1 and a connecting point of both the coils is used as an input terminal and an inductance element inserted between both terminals being output terminals of the distribution transformer. CONSTITUTION:The distribution transformer 2 is the series connection of a couple of coils 31, 32 whose winding ratio is nearly 1:1 and both the coils 31, 32 are wound in opposite phase to the connection point. That is, both ends of both the windings 11a, 11b are connected electrically to form the input terminal, the one winding 11a is penetrated through one terminal in axial direction of a ferrite bead 10 to form the one coil 31 and the other winding 11b is penetrated from the outer terminal in the axial direction of the ferrite bead 10 to form the other coil 32. Thus, the coupling loss is increased much at a high frequency band and the distributor with high performance and less leakage loss between the output terminals is obtained as a distributor for television broadcast wave reception.
