PROBLEM TO BE SOLVED: To provide a choke coil structure for a splitter in which longitudinal current unbalance attenuating characteristics of a high-pass region are improved. SOLUTION: The choke coil 11 includes a core 16 mounted in the hollow part 15 of a bobbin, and a plurality of terminals 14 provided under the bobbin. The bobbin 12 is divided in a coil winding widthwise direction from the divided wall 13 of the part of the bobbin 12. An inner layer N2, an intermediate layer N3 and an outer layer N1 are wound from a center of the figure of a coil winding stem in a divided split spool, and a three-circuit coil is constituted of the coils of each hierarchy.
