PURPOSE:To enable to fix simply a loading material in a kerf without using an adhesive, etc. by a method wherein a lead wire or a terminal in the kerf is fixed according to a supersonic heating means, a heater heating means or a high-frequency heating means. CONSTITUTION:A coil bobbin 1 is provided with a hollow trunk part 2, and a flange 3 formed in one body to the edge part of the trunk part 2 thereof, coil lead wires 5 are led out from kerfs 4 formed in the flange 3 thereof, then a horn 6 is approached both the sides of the kerfs 4 of the flange 3, and moreover made to come in contact therewith, and when the horn 6 is driven, the contacting parts of the flange with the horn 6 are softened or molten by frictional heat according to the vibration of the horn 6. At this case, when the horn 6 is pressed to be adhered by pressure against the flange 3, the mutually facing projecting parts of the horn 6 sink into the edge parts of the flange 3, the resin constructing the flange 3 is swollen inside of the kerfs 4 by nearly the amount of sinking thereof, breadths of the kerfs 4 are narrowed, or the kerfs 4 are closed to be adhered according to circumstances, and therefore the lead wires 5 can be fixed easily. |
