The length from 4B10 to the bent part 486, especially the length of the part 4B7 perpendicular to the tube axis, is the length of the loop part 4 when the reception frequency band is wide band.
The need to increase the internal space area of B does not necessarily result in an appropriate dimension for matching, and therefore the impedance seen from the bent part 4B6 to the tip 4B10 is generally smaller than the impedance seen from the bent part 486 to the coaxial connector 6 side. As a result, there is a problem in that impedance matching seen from the coaxial portion 7 on the coaxial connector 6 side becomes difficult.
