Abstract
A high-frequency transmission line having low alternate current (AC) resistance is provided. One aspect of the present invention is a high-frequency transmission line disposed along a surface of an insulating support, wherein, letting F [Hz] be the frequency of an AC electric signal transmitted by the high-frequency transmission line and Ms [Wb/m] be the saturation magnetization per unit area, the frequency value F and the saturation magnification value per unit area Ms satisfy the following expression (1): Ms≦(1.5×102)/F+5.7×10−8.
