しまう。2. Description of the Related Art Conventionally, this type of toroidal coil is shown in FIG.
As shown in the figure, the winding end of the copper wire 3 was simply inserted into the hole of the base 2 and pulled out from below. As the winding material, a soft material such as a copper wire 3 is usually used, and in a type that is pulled out as it is, the terminal is bent, and the pitch α of the substrate mounting is not constant. This poses a serious problem when mounting on a substrate by an automatic mounting machine. On the other hand, as shown in FIG. 5, it is adopted that the pins 4 are buried in the base 2 to keep the pin pitch constant. However, since current flows through the buried pins 4, the material of the pins becomes a problem. That is, a material having a low DC resistance is required (in order to avoid a loss due to heat generation) in spite of the condition that a hard pin is used, which is an inexpensive demand. Furthermore, since the connection called "kage" is established, the height of the product is increased by the keg portion β.
