接続部７から外れないようになつている。(Example) Examples of the present invention will be described below with reference to the drawings. 1 and 2 show an embodiment of the present invention. In the drawing, 1 is an inductor body in which a wire winding 3 with a diameter of 0.3 to 0.5 mm is wound around a toroidal core 2 made of ferrite; 4 is a substantially rectangular parallelepiped insulator that holds the inductor body 1; The inductor main body 1 is fitted and held in a recess 5 formed on the side surface of the body 4, and on both sides of the recess 5, the upper end protrudes as a connection part 7 for the terminal 6 of the winding 3, and the lower end is a lead. Terminals 9, 9 of a wire having a diameter of 0.8 mm, for example, led out as the portion 8 are buried therein. The insulator 4 also has a groove 1 that communicates from the recess 5 to the upper surface in order to connect the terminal 6 of the winding 3 to the connection part 7 of the terminal 9.
0 and 10 are formed, and a protrusion 12 is formed on the side surface of the protruding base portion 11 on the upper surface, which faces the intermediate portion of the connecting portion 7 of the terminal 9. The distance between the tip of the protrusion 12 and the connection part 7 of the terminal 9 is formed to be slightly narrower than the diameter of the end 6 of the winding 3, and the protrusion 12 is press-fitted into the distance and entwined with the base of the connection part 7 of the terminal 9. When the terminal 6 of the winding 3 moves within the recess 5 of the inductor body 1 when the insulator 4 is turned over so that the terminal 6 is soldered to the terminal 7 so that the terminal 7 is on the bottom, the terminal 6 of the winding 3 is moved inside the recess 5 of the inductor body 1 and the terminal 6 is soldered to the terminal 7. It's designed to stay in place.

In the embodiment described above, the protrusion 12 was formed on the side surface of the protruding base portion 10, but the protrusion may be formed on the upper surface of the insulator 4 outside the connecting portion 7 of the terminal 9.
