PURPOSE:To set excellent matching state of both coils and to contrive the decrease of the number of components by forming a delay line coil and a peaking coil to the groove of one and the same bobbin made of an insulating resin member. CONSTITUTION:A delay line coil 7 is formed by providing a conductor having an insulation film, a signal winding and an earth winding to the groove between flanges of an insulating resin made bobbin 1 in a color TV receiver or the like. A perking coil 8 is formed to other groove of the bobbin 1 and since the coil 8 used together with the coil 7 is formed on one and same bobbin, the matching state of both coils is set in an excellent way and number of components is decreased in comparison with the case having independent coils.
