にメルフ抵抗体３を装着したもの等が挙げられる。As is well known, coil elements are used as choke coils at high frequencies and the like. As such a coil element, conventionally, as shown in FIG. 2, a cylindrical coil 1 made of an insulating coated copper wire and a magnetic body 2 such as ferrite is attached to the cylindrical coil 1, or as shown in FIG. The thing etc. which attached the melf resistor 3 inside are mentioned.

い。However, according to the conventional coil element, when the surface mounting is performed on the mounting substrate 4,
Since there is a space between the both ends to be the terminal portion and the mounting substrate 4, when the reflowing is performed, the terminal side having many solder pastes 5 is pulled. Further, as shown in FIG. 5, there is a case where both terminals are surely not provided with the solder paste 5. Furthermore, since the terminal portion is subjected to soldering by removing the insulating coating of the copper wire after or before inserting the core, it takes time and the workability is poor.
