The height becomes low. On the other hand, since the base end portion of the lead terminal is embedded in the side wall of the recess, the fixing strength is not impaired. When the base end of the plate-shaped lead terminal is bent in the thickness direction, the fixing strength of the base end of the lead terminal embedded in the side wall is improved and the distance between the lead terminals is narrower than that in the case where the wings are projected on both sides.

In FIG. 6, 1 is a coil body, 2 is an insulating base,
3 is a cover. The coil body 1 is formed by winding three wires 5 around a toroidal core 4 made of ferrite, for example, and windings 6 wound on the toroidal core 4. The coil body 1 is formed on the upper surface of an insulating base 2 made of synthetic resin, for example. It is accommodated and fixed in the recess 7 formed. This insulating base 2 is fixed by embedding the base end portions of three plate-shaped lead terminals 9, 9, 9 in opposite side walls 8 1 , 8 1 of the concave portion 7 respectively. The ends 10 of the windings 6 are twisted and soldered to the bases of the lead terminals 9, 9, 9. Plate-shaped lead terminal 9
Has its base end bent almost at a right angle in its thickness direction,
The other end is bent so as to be located slightly below a plane including the lower surface of the insulating base 2. The opposite side walls 8
1 and 8 1 are higher than both side walls 8 2 and 8 2 facing each other in the direction perpendicular to this, and a pair of protrusions 11 and 11 are formed on the upper surface thereof.
Notches 12 and 12 are formed in the lower portions of both outer walls of the side walls 8 1 and 8 1 , respectively. The cover 3 has a pair of hanging pieces 13 and 13 on both sides thereof, and locking claws 14 and 14 are provided at the lower ends thereof.

After connecting, the cover 3 is covered on the insulating base 2, and the pair of hanging pieces 13, 13 on both sides are engaged with the notches 12, 12 of the insulating base 2 to lock the cover 3. According to this configuration, the drawn-out portion of the terminal 10 of the winding wire 6 from the insulating base 2 has the cover 3
When it is locked to the insulating base 2, it is not pushed by the cover 3, so that there is no disconnection. Since the common mode choke coil of this embodiment has three windings for stereo audio signals and for grounding, three plate-shaped lead terminals are provided for each, but when a winding for video signals is also provided. For each, four plate-shaped lead terminals may be provided.
