ンダクターを構成していた。Conventional technology Conventional chip inductors are shown in Figures 4 and 5.
The structure was as shown in Figure 6. That is, in order to align the drum-shaped core 12 and the terminals 9, both sides of the drum-shaped core 12 are made into flat surfaces, and the electrodes 14 are bonded, and the coil leads 10 wound in the grooves of the drum-shaped core 12 are connected to the electrodes 14. A chip inductor was constructed by soldering scissors with external connection terminals 9 and molding with resin 15.

後、外部端子４を折曲げ第３図のようにする。Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings. The protrusions 5 on both sides of the drum core shown in FIG. 1 are fitted into the holes of the terminals 4 for alignment. The terminal 4 and the drum-shaped core 1 are fixed with adhesive or the like. The coil lead 6 of the coil 2 wound around the drum-shaped core 1 to form an inductance is electrically connected to the coil lead winding of the terminal 4.
After molding this with resin as shown by the dotted line in FIG. 2, the external terminal 4 is bent to form the shape shown in FIG. 3.
第１図は単体の端子の図面であるが作業性等を
考え連続端子にしてもよい。 Although FIG. 1 shows a single terminal, a continuous terminal may be used in consideration of workability and the like.
発明の効果
