The phase-shifting circuit further includes a transformer unit 7 for matching impedance between the overlapping section 5 and non-overlapping section 6 where the signal conductor 2 and the dielectric body 3 do not overlap each other, said transformer unit being provided at end sections of the dielectric body 3, said end sections being on the input side and output side of the signals. The transformer unit 7 includes a high-impedance section 7a that is provided on the overlapping section 5 side, and a low-impedance section 7b, which is provided on the non-overlapping section 6 side of the high-impedance section 7a, and which has a lower characteristic impedance than the high-impedance section 7a.
