しまい断線か発生してしまうということかあった。[Problems to be Solved by the Invention] However, in the above conventional example, the terminal is only wrapped around the terminal conductor, so sometimes when soldering with a solder layer, there is no part to block the solder. There was a problem with soldering due to position and difficulty. This soldering may vary in position, and if it is too deep, the soldering in the hollow part 1b between the coil wire 1 or the winding part 1a and the winding part 1c will become thinner due to the high heat of the time, resulting in wire breakage. There were times when I ended up doing it.

If space is taken for winding the end of the coil wire 1, the terminal holding portion 2a of the bobbin that holds the terminal conductor portion 3 of the bobbin 2 will be
As a result, the holding strength of the terminal conductor portion 3 becomes weaker, leading to problems such as terminal disconnection and terminal bending.
